In Exodus chapter twenty, verse seven, making use of the name Lord or God in a light and trifling way, without any show of reverence and affection, should never be mentioned in a grave and serious manner. Taking God’s name “in vain” includes making a false promise by it. Pronouncing it insincerely or thoughtlessly, by cursing or blaspheming, should not be done by anyone. God’s name must be hallowed, honored, and respected as profoundly sacred, and only in a holy manner.
Jewish writers interpret taking the name of God in vain as swearing lightly, rashly, or falsely. However, all profane oaths, imprecations, and curses by the title of the Holy One, with mouths of wicked men are full of, so swearing by it in matters trivial, and of no importance. Still, using the name of the Lord should be in situations of moment and consequence, for the confirmation of a thing, and putting an end to strife, and where matters cannot be determined and decided without an appeal to God. Care should be by a man who considers that which is right and not false: for false swearing, or perjury, is a very grievous sin, and as it is strictly forbidden, and severely punished by the Lord.
The songwriter states that “the name of the Lord is a strong tower, and the righteous run into it and they are safe.” However, the people that do not know God tend to use His name like it is a regular conversation and treat it like nothing. The public says, “oh my God,” or “oh Jesus,” or blurts out “Jesus Christ,” to a situation they deem bad, wrong, unfortunate, or typically when a mistake occurs. Participating in such verbal activity sets up the others to follow the same path of the world to be punished by God.
