The Third Commandment states: lo tissa et shem Adonai Elohekha lashav, “You shall not lift up (lit. “carry”) the Name of the LORD your God in vain” (Exod. 20:7). Note that the Hebrew word lashav (לַשָּׁוְא), usually translated “in vain” in English, means in an empty or thoughtless manner (the LXX translates it as ἐπὶ ματαίῳ, “worthlessly” or “thoughtlessly”), though the word might also be rendered as “for show,” that is, insincerely or for sake of others. Obviously “lifting up the Name” of God ‘lashav’ includes invoking the Divine Presence in profane and vulgar ways, but it also includes “lip-service” expressions of faith, mechanical confessions, heartless acts of service, and so on. “Lifting up the Name” should never be used as a “weapon” against others, nor should it ever be used to justify or practice violence. You cannot “call upon God’s Name” in the truth without first exercising genuine reverence by recognizing the sacredness of life, the value of other people, and the LORD’s all-consuming glory, love, and power…
Reverencing the Name of the LORD means being in a personal, vital, and all-important relationship with the truth. The Holy Spirit is called the Spirit of Truth (רוּחַ הָאֱמֶת). This means understanding God’s character as “merciful and gracious, slow to anger, and abounding in steadfast love and faithfulness, extending kindness to the thousandth generation, forgiving iniquity, transgression, and sin” (Exod. 34:6-7). Since the Hebrew idea of word (דָּבָר) is coextensive with truth (i.e., “thing”), Yeshua is called the Word of God (דְּבַר אֱלהִים) who represents the Name of God to all who trust in Him (John 17:26, Heb. 1:3). Indeed Yeshua is the true Name of God, the “substance” (being) of God, the “exact imprint and representation of His nature,” and so on. “His eyes are like a flame of fire, and on his head are many diadems, and he has a name written that no one knows but himself. He is clothed in a robe dipped in blood, and the name by which he is called is ‘The Word of God” (Rev. 19:12-13).
