Esias 50:7

7 but the Lord God became my helper; therefore I was not ashamed, but I set my face as a solid rock; and I know that I shall never be ashamed,

Esias 50:7 In-Context

5 and the instruction of the Lord, even the Lord, opens mine ears, and I do not disobey, nor dispute.
6 I gave my back to scourges, and my cheeks to blows; and I turned not away my face from the shame of spitting:
7 but the Lord God became my helper; therefore I was not ashamed, but I set my face as a solid rock; and I know that I shall never be ashamed,
8 for he that has justified me draws near; who is he that pleads with me? let him stand up against me at the same time: yea, who is he that pleads with me? let him draw nigh to me.
9 Behold, the Lord, the Lord, will help me; who will hurt me? behold, all ye shall wax old as a garment, and a moth shall devour you.
