Nehemiah 4:4 (KJV)

And he spake before his brethren and the army of Samaria, and said, What do these feeble Jews? will they fortify themselves? will they sacrifice? will they make an end in a day? will they revive the stones out of the heaps of the rubbish which are burned?

Now Tobiah the Ammonite was by him, and he said, Even that which they build, if a fox go up, he shall even break down their stone wall.

Hear, O our God; for we are despised: and turn their reproach upon their own head, and give them for a prey in the land of captivity:

And cover not their iniquity, and let not their sin be blotted out from before thee: for they have provoked thee to anger before the builders.

So built we the wall; and all the wall was joined together unto the half thereof: for the people had a mind to work.
