branch, bud, that which (where) grew (upon), spring(-ing)

Concise Bible Dictionary:

A title of the Lord Jesus, which He will bear in connection with Israel in the future (Isa. 4:22In that day shall the branch of the Lord be beautiful and glorious, and the fruit of the earth shall be excellent and comely for them that are escaped of Israel. (Isaiah 4:2); Jer. 23:5; 33:155Behold, the days come, saith the Lord, that I will raise unto David a righteous Branch, and a King shall reign and prosper, and shall execute judgment and justice in the earth. (Jeremiah 23:5)
15In those days, and at that time, will I cause the Branch of righteousness to grow up unto David; and he shall execute judgment and righteousness in the land. (Jeremiah 33:15); Zech. 3:88Hear now, O Joshua the high priest, thou, and thy fellows that sit before thee: for they are men wondered at: for, behold, I will bring forth my servant the BRANCH. (Zechariah 3:8); Zech. 6:12-1312And speak unto him, saying, Thus speaketh the Lord of hosts, saying, Behold the man whose name is The BRANCH; and he shall grow up out of his place, and he shall build the temple of the Lord: 13Even he shall build the temple of the Lord; and he shall bear the glory, and shall sit and rule upon his throne; and he shall be a priest upon his throne: and the counsel of peace shall be between them both. (Zechariah 6:12‑13)). In two of the passages the words “unto David” are added, which coincides with the Lord Jesus being the “offspring” (which is a similar word to “branch”) as well as the “root” of David. He will be a “righteous Branch and a King.” He will “build [or advance in honor] the temple of Jehovah; and he shall bear the glory, and shall sit and rule upon his throne; and he shall be a priest upon his throne: and the counsel of peace shall be between them both” (Compare Psa. 85 and 87). It is a description of the Lord Jesus in the millennium.
