Deuteronomy 7:26
Neither shalt thou bring an abomination into thine house, lest thou be a cursed thing like it: but thou shalt utterly detest it, and thou shalt utterly abhor it; for it is a cursed thing. Neither shalt thou bring an abomination into thine house, lest thou be a cursed thing like it: but thou shalt utterly detest it, and thou shalt utterly abhor it; for it is a cursed thing.
The command belongs to the requirements God gave His ancient chosen people in Deuteronomy 4 through 8, including the whole of chapter 7 together with chapters 1 and 8, to make them a holy people to Himself. Keeping His commandments and judgments was tied to His covenant mercy and blessings. Prosperity depended on strict obedience to every principle He had given, and those directions are to be observed carefully, from the greatest to what may seem least.
The verse forbids bringing into the house anything associated with the abominable practices of the Canaanites, especially idolatrous objects, because they are detestable and cursed. Whoever does so becomes a cursed thing like them. Such things must therefore be utterly detested and abhorred and completely rejected. The warning against idolatry should be made visible to readers, which supports removing images of heathen shrines from church publications and placing God's commandments before the people instead.
For parents the verse means taking every precaution to keep what is objectionable out of the house so that children do not grow up with objectionable traits of character. It calls them to control themselves for their Creator and Redeemer, to cleanse the soul-temple, to trim the inner lamp, and to reveal piety, virtue, and godliness in the home life. No splendid service is accepted unless the one who offers it first surrenders the whole soul to God, for unless the root is holy there can be no acceptable fruit. Unless parents so prepare for the present and the future life, they will not be admitted into the city of God.
The command is to be studied with profit and read and obeyed now as admonition for those upon whom the ends of the world are come. The day of God's great final review is near, when all must stand before the Judge of all the earth to answer for their deeds. The present is the time of investigation, when before that review every character will have been investigated and every case decided for eternity.
