Matthew Poole and continuators on Deuteronomy 24:13

13 In any case thou shalt deliver him the pledg again, when the sun goeth down, that he may sleep in his own raiment, and bless thee : and it shall be righteousness unto thee before the LORD thy God .

Instrumentally, as ministers are said to convert and save sinners, to wit, bring down the blessing of God upon thee by his prayers: for though his prayers, if he be not a good man, shall not avail for his own behalf, yet they shall avail for thy benefit.

(i. e.) Esteemed and accepted by God as a work of righteousness, or holiness, or goodness and mercy, which oft is called righteousness, as Psal. 112. 9. Prov. 10. 2. Dan. 4. 27.
