Jehovah is the personal name of God, as found in the Bible. (Exodus 6:3; Psalm 83:18) A witness is a person who proclaims views or truths of which he is convinced.
Thus, our name Jehovah’s Witnesses designates us as a group of Christians who proclaim the truth about Jehovah, the Creator of all things. (Revelation 4:11) We witness to others by the way we live our lives and by sharing with them what we’ve learned from the Bible.—Isaiah 43:10-12; 1 Peter 2:12
