7 When you happen on someone who's in trouble or needs help among your people with whom you live in this land that God, your God, is giving you, don't look the other way pretending you don't see him. Don't keep a tight grip on your purse. 8 No. Look at him, open your purse, lend whatever and as much as he needs. 9 Don't count the cost. Don't listen to that selfish voice saying, "It's almost the seventh year, the year of All-Debts-Are-Canceled," and turn aside and leave your needy neighbor in the lurch, refusing to help him. He'll call God's attention to you and your blatant sin. 10 Give freely and spontaneously. Don't have a stingy heart. The way you handle matters like this triggers God, your God's, blessing in everything you do, all your work and ventures.
Matthew Henry's Commentary on Deuteronomy 15:7-10
Commentary on Deuteronomy 15:1-11
(Read Deuteronomy 15:1-11)
This year of release typified the grace of the gospel, in which is proclaimed the acceptable year of the Lord; and by which we obtain the release of our debts, that is, the pardon of our sins. The law is spiritual, and lays restraints upon the thoughts of the heart. We mistake, if we think thoughts are free from God's knowledge and check. That is a wicked heart indeed, which raises evil thoughts from the good law of God, as theirs did, who, because God had obliged them to the charity of forgiving, denied the charity of giving. Those who would keep from the act of sin, must keep out of their minds the very thought of sin. It is a dreadful thing to have the cry of the poor justly against us. Grudge not a kindness to thy brother; distrust not the providence of God. What thou doest, do freely, for God loves a cheerful giver, 2 Corinthians 9:7.
