fōrth : "Forth," adverb (from "for"), signifies movement (1) forward, (2) out of, (3) beyond a certain boundary. In a few instances in the Old Testament it is the translation of the preposition ‛al , properly "above," "upon" ( 2 Kings 11:15; 2 Chronicles 23:14; Amos 7:17 the King James Version), and of ḥūc , "without" ( Genesis 39:13; Judges 19:25 ). "Forth" is often used as an expletive of various verbs, as "break (forth)," "bring (forth)," "call (forth)," etc. In the Gospel of John it is the translation of éxō , "without," as "Lazarus, come forth" ( John 11:43; so John 15:6; John 19:4 the King James Version, etc.; also Acts 5:34; Acts 9:40 ). "Stand forth" in Mark 3:3 is the translation of égeire eis tó méson , margin "Arise into the midst." the Revised Version (British and American) has a great many changes, frequently substituting "out," "away," "abroad," etc.; "forth from" for "out of" ( Job 41:21; Isaiah 45:23 ); "spread forth" for "stretched out" ( Psalm 44:20; Psalm 88:9; Psalm 136:6 ), etc. In Colossians 1:6 , for "bringeth forth fruit" the Revised Version (British and American) reads "bearing fruit."
