The answer
The word Nazarene or the Greek Nazaraios is applied to our Lord Christ only once as in (Mt 2:23). According to the Easton's Bible dictionary, this name is an allusion to the Hebrew word 'netser' which signifies a branch or sprout. It is so applied to the Messiah i.e., He whom the prophets called the Netse, the 'Branch' "There shall come forth a Rod from the stem of Jesse, And a Branch shall grow out of his roots" (Isa 11:1).In the place where we read and translate, "There shall come forth a Rod out of the stem of Jesse, and a Branch shall grow out of his roots," in the Hebrew idiom it is written thus, "There shall come forth a rod out of the root of Jesse and a Nazarene shall grow from his root." (Jerome, Letter 47:7)
Zechariah prophesied about the Branch who was our Lord Jesus: "Behold, a man whose name is Branch, for He will branch out from where He is; and He will build the temple of the Lord" (Zech 6:12). Other Old Testament passages regarding branch are: Isa 4:2; 53:2; Jer 23:5; 33:15; Zech 3:8.
