A sprouting or growth from the ground. Prophetically, 'the Branch' (tsemach) is a key messianic title — the shoot from David's line who would reign in righteousness (Jer 23:5; Zech 3:8; 6:12).
The messianic 'Branch' passages are among the OT's clearest prophecies. Zechariah 6:12-13 depicts 'the man whose name is Branch' who will build the temple and rule — fulfilled in Jesus.
Four 'Branch' prophecies (Isa 4:2; Jer 23:5; Zech 3:8; 6:12) each highlight a different aspect of Messiah — Branch of the LORD, righteous Branch, Servant Branch, Builder Branch.
