8 you shall not yield to him or listen to him, nor shall your eye pity him, nor shall you spare him, nor shall you conceal him;

Matthew Henry's Commentary on Deuteronomy 13:8

Commentary on Deuteronomy 13:6-11

(Read Deuteronomy 13:6-11)

It is the policy of Satan to try to lead us to evil by those whom we love, whom we least suspect of any ill design, and whom we are desirous to please, and apt to conform to. The enticement here is supposed to come from a brother or child, who are near by nature; from a wife or friend, who are near by choice, and are to us as our souls. But it is our duty to prefer God and religion, before the nearest and dearest friends we have in the world. We must not, to please our friends, break God's law. Thou shalt not consent to him, nor go with him, not for company, or curiosity, not to gain his affections. It is a general rule, If sinners entice thee, consent thou not, Proverbs 1:10. And we must not hinder the course of God's justice.
