Speak to him and say

"Speak to Joshua and say"

his name is Branch

The word "Branch" refers to a messianic figure that would serve as king over Yahweh's people. Yahweh speaks of this person as if he were a branch that grows out from a tree. Since the word "Branch" is a title, it should be translated with an equivalent word in your language. See how you translated this name in Zechariah 3:8. (See: rc://en/ta/man/jit/figs-metaphor)

He will grow up where he is

The phrase "grow up" refers to the growth of a plant, and so continues the metaphor of this person as a "Branch." This likely refers to this person appearing or coming into power as the one who would supervise the rebuilding of the temple. (See: rc://en/ta/man/jit/figs-metaphor)
