Psalms 49:7

“None [of them] can by any means redeem his brother, etc.] That is, “with their substance”, or “riches”, as the Targum and Jarchi supply. Some, according to the order of the words in the original, render them, “a brother redeeming cannot redeem a man”, or “anyone” f644: but, as Aben Ezra observes, ja, “a brother”, is the effect, and çya, “a man”, is the cause.

“None of them can bid any means redeem his brother - None of those who are rich.

The whole expression is emphatic: “redeeming he cannot redeem;” that…”

“Redeem - Neither from the first death, nor from the second. Brother - Whom he would do his utmost to preserve. Psalms 49:8”
