Hebraic Insight…
The third of the ten mitzvot (commandments) is, “Thou shalt not take the name of the LORD thy God in vain” (KJV). Many of the Jewish sages taught that the word translated “name” powerfully refers to the character or reputation of the one who bears it. The revealed name of the LORD— thus can be understood as the invocation for the very presence of God Himself. The word translated “in vain” probably comes from another word that pictures a rushing and destructive storm (sho-ah). One way to understand this mitzvah, then, is that we should never invoke Adonai’s name in a thoughtless, careless, or “stormy” manner (for this reason, orthodox Jews never pronounce the literal name, but substitute the word “Adonai” or “HaShem” instead).
When we call upon the LORD, we are actually invoking the one true God of the universe to manifest Himself to us. Since God is faithful and will be true to His name, He will really be present whenever He is called. This is serious business, and we should never take it lightly.
