Speaking of the Lord Jesus Christ.
Isa 11:1 And there shall come forth a rod out of the stem of Jesse, and a Branch shall grow out of his roots:
Isa 11:2 And the spirit of the LORD shall rest upon him, the spirit of wisdom and understanding, the spirit of counsel and might, the spirit of knowledge and of the fear of the LORD;

Isa 4:3 And it shall come to pass, that he that is left in Zion, and he that remaineth in Jerusalem, shall be called holy, even every one that is written among the living in Jerusalem:
The remnant that are trusting in the Messiah, shall live a life separated from the world and the bad lusts of the flesh. They shall be, holy, separated unto God. This is to be the life of the believer, the redeemed in Christ Jesus. We should not be as the proud, the arrogant and the sexually immoral, that the proud women of Zion represented.
2 Cor 6:17 Wherefore come out from among them, and be ye separate, saith the Lord, and touch not the unclean thing; and I will receive you,
We are the branches of the Branch. He is the vine and we are to be like him. The blood of the Vine (Lamb) flows, to make us pure and able to bring forth His good fruit.
