Esias 41:7

7 The artificer has become strong, and the coppersmith that smites with the hammer, forges also: sometimes he will say, It is a piece well joined: they have fastened them with nails; they will fix them, and they shall not be moved.

Esias 41:7 In-Context

5 The nations saw, and feared; the ends of the earth drew nigh, and came together,
6 every one judging for his neighbor and to assist his brother: and one will say,
7 The artificer has become strong, and the coppersmith that smites with the hammer, forges also: sometimes he will say, It is a piece well joined: they have fastened them with nails; they will fix them, and they shall not be moved.
8 But thou, Israel, art my servant Jacob, and he whom I have chosen, the seed of Abraam, whom I have loved:
9 whom I have taken hold of from the ends of the earth, and from the high places of it I have called thee, and said to thee, Thou art my servant; I have chosen thee, and I have not forsaken thee.
