1 Samuel 18:8 Douay-Rheims

And Saul was exceeding angry, and this word was displeasing in his eyes, and he said: They have given David ten thousands, and to me they have given but a thousand; what can he have more but the kingdom?

“It is usual, indeed, with persons of a weaker character, to be so built up in confidence by certain individuals who are caught by heresy, as to topple over into ruin themselves. How does it come to pass, they ask, that this woman or that man, who were the most faithful, the most prudent and the most approved in the church, have gone over to the other side? Who that asks such a question does not in fact reply to it himself, to the effect that men whom heresies have been able to pervert ought never to have been esteemed prudent or faithful or approved? This again, I suppose, is an extraordinary thing, that one who has been approved should afterwards fall back? Saul, who was good beyond all others, is afterwards subverted by envy. David, a good man "after the Lord's own heart." is guilty afterwards of murder and adultery. Solomon, endowed by the Lord with all grace and wisdom, is led into idolatry by women. For to the Son of God alone was it reserved to persevere to the last without sin.”

“And Saul was very wroth, and the saying displeased him,.... Partly because they called him plain Saul, and not King Saul; did not give him his royal title, which might serve to strengthen his suspicion, after suggested; and chiefly because they attributed a greater number of slain to David than to him, as follows: and he said, they have ascribed unto David ten thousands, and to me they ascribed but thousands; and so had given more honour to an inferior officer than to the commander-in-chief, more to a subject than to a sovereign: and what can he have more but the kingdom? there is nothing left out of their song, and nothing remains to be given him but that; some think that Saul knew, by the prudent behaviour of David, and the favour he was in with God and men, and by these commendations of the women, that the kingdom would be his; and that the words of Samuel were true, and would be confirmed, that the kingdom would be rent from him, and given to his neighbour better than he. This clause, with Sa1 18:9, is left out of the Greek version, according to the Vatican copy.”

“A thousand. These women were guilty of an indiscretion, through excess of zeal, as it is always displeasing for the sovereign to hear any of his subjects preferred before him. (St. Chrysostom, hom. i. de Saul.) — The jealousy of Saul was the more excited, as he had been threatened with the loss of his kingdom, and perceived in David all the qualifications of a king. A malo principe tanquam successor timetur quisquis est dignior. (Pliny in Traj.) — But was David responsible for what was spoken in his praise? (Calmet) — The Vatican Septuagint omit what follows till ver. 12. “And Saul feared David, ( 13 ) and he removed,” &c. The Alexandrian copy agrees with the Vulgate. (Haydock) — Those who are proud, cannot bear the praises of others. (Worthington)”
