The third commandment forbiddeth all profaning or abusing of any thing whereby God maketh himself known. The reason annexed to the third commandment is, that however the breakers of this commandment may escape punishment. The first hath respect to the object of worship, forbidding us to worship any other but God. The second respects the means of worship, forbidding us to worship God by any other means than what he hath prescribed. But the third respects the manner of his worship, forbidding all careless, or profane use of his name, and commanding an holy reverence from us in all our solemn addresses to him, or ordinary mention of his name.
Thine enemies take thy name in vain.
The curse of God enters into such families. Let it come now. Except they repent and reform. By swearing, and lying, and killing, and stealing, and committing adultery, they break out, arid blood toucheth blood. Therefore shall the land mourn, and every one that dwelleth therein shall languish, with the beasts of the field, and with the fowls of heaven, yea, the fishes of the sea also shall be taken away.
