Esias 51:14

14 For in thy deliverance he shall not halt, nor tarry;

Esias 51:14 In-Context

12 I, I, am he that comforts thee: consider who thou art, that thou wast afraid of mortal man, and of the son of man, who are withered as grass.
13 And thou hast forgotten God who made thee, who made the sky and founded the earth; and thou wert continually afraid because of the wrath of him that afflicted thee: for he counselled to take thee away, yet now where is the wrath of him that afflicted thee?
14 For in thy deliverance he shall not halt, nor tarry;
15 for I am thy God, that troubles the sea, and causes the waves thereof to roar: the Lord of hosts is my name.
16 I will put my words into thy mouth, and I will shelter thee under the shadow of mine hand, with which I fixed the sky, and founded the earth: and shall say to Sion, Thou art my people.
