The wicked borroweth, and payeth not again. The wicked man borrows with a light heart, though he may have no prospect of ever being able to repay. Living under God's curse (Psalms 37:22), he is for the most part not able to repay; when he happens to be able, he is often not willing.
But the righteous showeth mercy, and giveth (comp. Psalms 112:5, Psalms 112:9). The righteous has not often need to borrow (see Deuteronomy 15:6; Deuteronomy 28:12, Deuteronomy 28:44). Rather, he lends and gives freely.
