Esias 50:9

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.

Esias 50:9 In-Context

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.
10 Who is among you that fears the Lord? let him hearken to the voice of his servant: ye that walk in darkness, and have no light, trust in the name of the Lord, and stay upon God.
11 Behold, ye all kindle a fire, and feed a flame: walk in the light of your fire, and in the flame which ye have kindled. This has happened to you for my sake; ye shall lie down in sorrow.
