Genesis 19:17 Douay-Rheims

And they brought him forth, and set him without the city: and there they spoke to him, saying: Save thy life: look not back, neither stay thou in all the country about: but save thyself in the mountain, lest thou be also consumed.

“On account of his hospitality and godliness, Lot was saved out of Sodom when all the country round was punished by means of fire and brimstone, the Lord thus making it manifest that He does not forsake those that hope in Him, but gives up such as depart from Him to punishment and torture. [Genesis 19:15-26, 2 Peter 2:6-9] For Lot's wife, who went forth with him, being of a different mind from himself, and not continuing in agreement with him [as to the command which had been given them], was made an example of, so as to be a pillar of salt unto this day. This was done that all might know that those who are of a double mind, and who distrust the power of God, bring down judgment on themselves and become a sign to all succeeding generations.”

המלט על נפשך ESCAPE FOR THY LIFE — Let it suffice you to save your lives; do not give a thought to your possessions. אל תבט אחריך LOOK NOT BEHIND THEE — You sinned with them but art saved through the merit of Abraham. It is not fitting that you should witness their doom whilst you yourself are escaping (Genesis Rabbah 50:11). בכל הככר IN ALL THE PLAIN — the plain of the Jordan (cf. Genesis 13:11). ההרה המלט ESCAPE TO THE MOUNTAIN — Flee to Abraham who is dwelling in the mountain — as it is said, (Genesis 12:8) “And he removed his tent thence unto the mountain”. He was still dwelling there, as it is said, (Genesis 13:3) “[And he went unto] … the place where his tent had been at first”, and although it is stated (Genesis 13:18) “And Abraham moved his tent etc.”, he had many tents and they stretched as far as Hebron. המלט ESCAPE — it means “slipping away” and similarly wherever this root מלט occurs in the Scriptures; in old French émisser. Examples are: (Isaiah 66:7) “she was delivered of (המליטה) a man child” i. e. the embryo slipped out of the womb; (Psalms 124:7) “[Our soul] is escaped (נמלטה) like a bird”; and (Isaiah 46:2) “They could not deliver (מלט) the burden”, i.e. discharge (make slip out) the burden of excrement in their bowel-passages.”

“LOOK NOT BEHIND THEE, NEITHER STAY IN ALL THE PLAIN. The purport of the verse is to state: “Do not stay in all the Plain and do not look behind you after you have been saved.” For as long as Lot had not reached the mountain, disaster would not overtake the inhabitants of Sodom. It is for this reason that Lot said, “And I cannot escape to the mountain, lest the evil overtake me when I am in the Plain since you will not extend the time for me more than a little, as you have said, Haste thee, escape thither.” Rabbi Abraham ibn Ezra said, “Look not behind thee, i.e., ‘thou and all who belong to thee.’ And similarly is the verse, Thou shalt not eat of it.” But what need is there for this interpretation? The punishment here was not because they would violate the warning of the angel by looking at them. Instead, the angel merely warned them on his own that punishment would overtake them for such a glance, and he warned Lot because of his merit, and all who listened and took warning saved their lives. Now as to the significance of the prohibition of looking, Rashi said: “You sinned with them but art saved through the merit of Abraham. You are not permitted to see their doom.” There is yet another matter. Looking upon the atmosphere of a plague and all contagious diseases is very harmful, and they may cleave to him. Even the thought of them is harmful. Therefore, the leper is isolated and dwells alone. Similarly, those who have been bitten by mad animals such as a mad dog and other animals besides, when they look into the water or any mirror, they behold in them the likeness of the offender, and as a result of this, they did just as the Rabbis have said in Tractate Yoma, and as the students of nature have mentioned. It was for this reason that Lot’s wife turned into a pillar of salt for the plague entered her mind when she saw the brimstone and salt are mentioned (Verse 24). Salt however is mentioned in Deuteronomy 29:22, in connection with the overthrow of Sodom. which descended upon them from heaven, and it cleaved to her. I am inclined to say that when G-d destroyed these cities the destroying angel stood between the earth and heaven, appearing in a flame of fire, as did the destroying angel whom David saw. Therefore, he prohibited them from looking. In Pirkei d’Rabbi Eliezer there is a similar text: “The angels said to them, ‘Do not look behind you since the Divine Presence of the Holy One, blessed be He, has descended to rain brimstone and fire upon Sodom and Gomorrah.’ The compassion of Edis, Lot’s wife, welled up for her married daughters who were in Sodom, and she looked behind her to see if they were following her. She thereupon saw the back of the Divine Presence, and she became a pillar of salt.””

“And it came to pass, when they had brought them forth abroad,.... Into the fields of Sodom, or the suburbs of it: that he said, escape for thy life; not one of the two men or angels that had been with him all the night past, for they had now left him, and were gone back to the city: but Jehovah the Son of God, who had been communing with Abraham, and now came to Sodom, and appeared to Lot, just at the time the two angels left him, and bid him escape with all haste, if he had any regard for his life, and that of those with him: look not behind thee; as showing any concern for his goods and substance he had left behind him, or for his sons-in-law, who refused to come with him, and much less for the wicked inhabitants of the city; and this command was not given to Lot only, but to his wife and daughters, as appears by the sequel: neither stay thou in all the plain: in the plain of Jordan, for the whole plain, and the cities in it, were to be destroyed: escape to the mountain, lest thou be destroyed, lest thou be consumed; the same mountain the kings of Sodom and Gomorrah, and they that were with them after the battle of the kings, fled to, Gen 14:10; here only he and his could be safe from the conflagration of the plain.”

“When they had brought them forth, etc. - Every word here is emphatic, Escape for thy Life; thou art in the most imminent danger of perishing; thy life and thy soul are both at stake. Look not behind thee - thou hast but barely time enough to escape from the judgment that is now descending; no lingering, or thou art lost! one look back may prove fatal to thee, and God commands thee to avoid it. Neither stay thou in all the plain, because God will destroy that as well as the city. Escape to the mountain, on which these judgments shall not light, and which God has appointed thee for a place of refuge; lest thou be Consumed. It is not an ordinary judgment that is coming; a fire from heaven shall burn up the cities, the plain, and all that remain in the cities and in the plain. Both the beginning and end of this exhortation are addressed to his personal feelings. "Skin for skin, yea, all that a man hath will he give for his life;" and self-preservation is the first law of nature, to which every other consideration is minor and unimportant.”

“When they left him here (הנּיח, to let loose, and leave, to leave to one's self), the Lord commanded him, for the sake of his life, not to look behind him, and not to stand still in all the plain (כּכּר, Gen 13:10), but to flee to the mountains (afterwards called the mountains of Moab). In Gen 19:17 we are struck by the change from the plural to the singular: "when they brought them forth, he said." To think of one of the two angels - the one, for example, who led the conversation - seems out of place, not only because Lot addressed him by the name of God, "Adonai" (Gen 19:18), but also because the speaker attributed to himself the judgment upon the cities (Gen 19:21, Gen 19:22), which is described in Gen 19:24 as executed by Jehovah. Yet there is nothing to indicate that Jehovah suddenly joined the angels. The only supposition that remains, therefore, is that Lot recognised in the two angels a manifestation of God, and so addressed them (Gen 19:18) as Adonai (my Lord), and that the angel who spoke addressed him as the messenger of Jehovah in the name of God, without its following from this, that Jehovah was present in the two angels. Lot, instead of cheerfully obeying the commandment of the Lord, appealed to the great mercy shown to him in the preservation of his life, and to the impossibility of his escaping to the mountains, without the evil overtaking him, and entreated therefore that he might be allowed to take refuge in the small and neighbouring city, i.e., in Bela, which received the name of Zoar (Gen 14:2) on account of Lot's calling it little. Zoar, the Σηγώρ of the lxx, and Segor of the crusaders, is hardly to be sought for on the peninsula which projects a long way into the southern half of the Dead Sea, in the Ghor of el Mezraa, as Irby and Robinson (Pal. iii. p. 481) suppose; it is much more probably to be found on the south-eastern point of the Dead Sea, in the Ghor of el Szaphia, at the opening of the Wady el Ahsa (vid., v. Raumer, Pal. p. 273, Anm. 14).”
