Psalms 49:7 - Matthew Poole's English Annotations on the Holy Bible

Redeem, to wit, from death, as appears from Psalms 49:9,10 &c.; neither from the first death, nor from the second, which he points at Psalms 49:14,19. His brother; whom he would do his utmost to preserve in life; and consequently not himself. But he seems to mention his brother rather than himself, because when his brother is sick, he being in health hath the full command and free use of all his wealth, and strength, and wit, and all other means of redeeming his brother; which he hath not, when he himself is dangerously or desperately sick. Nor give to God; the only Lord of life. and the Judge who hath passed upon him the sentence of death.
