Deuteronomy 13:8 Meaning and Commentary

Deuteronomy 13:8

Thou shall not consent unto him
To commit the idolatry enticed unto, or join with him in it:

nor hearken to him;
not so much as patiently to hear him, but at once express an abhorrence of and indignation at what he recommends:

neither shall thine eye pity him;
pitied he might be for his ignorance, stupidity, and wickedness, and on account of the miserable estate and condition he was in, and of those dreadful consequences which would follow upon it, if not converted from it; but no mercy was to be shown him on account of nearness of relation:

neither shall thou spare;
to reprove him sharply and to expose him to public vengeance:

neither shall thou conceal him;
neither him nor his sin, but make both public, acquaint others with it, and endeavour to bring him before the civil magistrate to be examined, tried, and judged; so far should they be from hiding his offence from others, or excusing and extenuating it, or from harbouring his person privately when sought for upon information.

Deuteronomy 13:8 In-Context

6 `When thy brother -- son of thy mother, or thy son, or thy daughter, or the wife of thy bosom, or thy friend who [is] as thine own soul -- doth move thee, in secret, saying, Let us go and serve other gods -- (which thou hast not known, thou and thy fathers,
7 of the gods of the peoples who [are] round about you, who are near unto thee, or who are far off from thee, from the end of the earth even unto the end of the earth) --
8 thou dost not consent to him, nor hearken unto him, nor doth thine eye have pity on him, nor dost thou spare, nor dost thou cover him over.
9 `But thou dost surely kill him; thy hand is on him, in the first place, to put him to death, and the hand of all the people last;
10 and thou hast stoned him with stones, and he hath died, for he hath sought to drive thee away from Jehovah thy God, who is bringing thee out of the land of Egypt, out of a house of servants;
