“Thus too it has been said that the Pharaoh of Egypt was a type of the devil, in that he cruelly ordered the males to be cast into the Nile and permitted the females to live. So too the devil, ruling over the great Egypt of the world "from Adam unto Moses," made an effort to carry off and destroy the male and rational offspring of the soul in the flood of the passions, while he takes delight in seeing the carnal and sensual offspring increase and multiply.”

בילדכן WHEN YE DO THE OFFICE OF A MIDWIFE — This word (the Piel) has the same force as בהולידכן (the Hiphil): when you assist them to give birth. על האבנים UPON THE STOOLS — the seat for the woman in the act of childbirth; in another passage (Isaiah 37:3) Scripture terms it מַשְׁבֵּר. Similar is, (Jeremiah 18:3) “He was at work on the אבנים" — the place of the vessels of (being produced by) the craftsmanship of the potter. אם בן הוא וגו IF IT BE A SON etc. — He was particular only about the male children because his astrologers had told him that there was to be born to a Hebrew woman a son who would become their deliverer (Exodus Rabbah 1:18). וחיה has the same meaning as ותחיה THEN SHE SHALL LIVE.”

“And he said, when ye do the office of a midwife to the Hebrew women,.... Deliver them of their children: and see them upon the stools; seats for women in labour to sit upon, and so contrived, that the midwives might do their office the more readily; but while they sat there, and before the birth, they could not tell whether the child was a son or a daughter; wherefore Kimchi (h) thinks the word here used signifies the place to which the infant falls down from its mother's belly, at the time of labour, and is called the place of the breaking forth of children, and takes it to be the "uterus" itself; and says it is called "Abanim", because "Banim", the children, are there, and supposes "A" or "Aleph" to be an additional letter; and so the sense then is, not when ye see the women on the seats, but the children in the place of coming forth; but then he asks, if it be so, why does he say, "and see them" there? could they see them before they were entirely out of the womb? to which he answers, they know by this rule, if a son, its face was downwards, and if a daughter, its face was upwards; how true this is, must be left to those that know better; the Jewish masters (i) constantly and positively affirm it: he further observes, that the word is of the dual number, because of the two valves of the womb, through which the infant passes: if it be a son, then ye shall kill him; give it a private pinch as it comes forth, while under their hands, that its death might seem to be owing to the difficulty of its birth, or to something that happened in it. This was ordered, because what the king had to fear from the Israelites was only from the males, and they only could multiply their people; and because of the above information of his magicians, if there is any truth in that: but if it be a daughter, then she shall live, be kept alive, and preserved, and brought up to woman's estate; and this the king chose to have done, having nothing to fear from them, being of the feeble sex, and that they might serve to gratify the lust of the Egyptians, who might be fond of Hebrew women, being more beautiful than theirs; or that they might be married and incorporated into Egyptian families, there being no males of their own, if this scheme took place, to match with them, and so by degrees the whole Israelitish nation would be mixed with, and swallowed up in the Egyptian nation, which was what was aimed at.

“Upon the stools - על האבנים al haobnayim. This is a difficult word, and occurs nowhere else in the Hebrew Bible but in Jer 18:3, where we translate it the potter's wheels. As אכי signifies a stone, the obnayim has been supposed to signify a stone trough, in which they received and washed the infant as soon as born. Jarchi, in his book of Hebrew roots, gives a very different interpretation of it; he derives it from בן ben, a son, or בנים banim, children; his words must not be literally translated, but this is the sense: "When ye do the office of a midwife to the Hebrew women, and ye see that the birth is broken forth, if it be a son, then ye shall kill him." Jonathan ben Uzziel gives us a curious reason for the command given by Pharaoh to the Egyptian women: "Pharaoh slept, and saw in his sleep a balance, and behold the whole land of Egypt stood in one scale, and a lamb in the other; and the scale in which the lamb was outweighed that in which was the land of Egypt. Immediately he sent and called all the chief magicians, and told them his dream. And Janes and Jimbres, (see Ti2 3:8). who were chief of the magicians, opened their mouths and said to Pharaoh, 'A child is shortly to be born in the congregation of the Israelites, whose hand shall destroy the whole land of Egypt.' Therefore Pharaoh spake to the midwives, etc."”

“The time, &c. Hebrew, “and you shall see them upon the two stones.” Abenaim. Jeremias (xviii. 3,) uses the same expression, speaking of a potter hard at work. (Calmet) — A woman, from whom nothing could be feared, to be reserved for service and for pleasure. (Menochius) — We must not obey princes in their unjust commands. (Acts iv, and Matthew x. 28.) (Worthington)”

“if it be a son, then ye shall kill him--Opinions are divided, however, what was the method of destruction which the king did recommend. Some think that the "stools" were low seats on which these obstetric practitioners sat by the bedside of the Hebrew women; and that, as they might easily discover the sex, so, whenever a boy appeared, they were to strangle it, unknown to its parents; while others are of opinion that the "stools" were stone troughs, by the river side--into which, when the infants were washed, they were to be, as it were, accidentally dropped.”
