A prayer for the poor who are afflicted. This is what the verse says (Proverbs 15:8): "The sacrifice of the wicked is an abomination to the Lord, but the prayer of the upright is His delight." The Lord does not require sacrifices or burnt offerings from the wicked. So what does He seek?
He seeks the prayer of the upright, as it says, "but the prayer of the upright is His delight." (Proverbs 15:8) Similarly, it says (Psalm 51:18), "For You do not desire sacrifice, or else I would give it; You do not delight in burnt offering." Another interpretation of "the sacrifice of the wicked is an abomination" is referring to Balaam and Balak, as it says (Numbers 23:14), "And he (Balaam) offered a bull and a ram as sacrifices."
So what does the prayer of the upright seek? It seeks what is expressed in Psalm 90:1, "A prayer of Moses the man of God."
