Nehemiah 4:1

But it came to pass, that when Sanballat heard that we
builded the wall
Or were building it; for as yet it was not finished, see ( Nehemiah 4:6 ) ,

he was wroth, and took great indignation;
inwardly, though outwardly he pretended to treat the work with contempt, as if it never would be accomplished, which yet he feared:

and mocked the Jews;
as a set of foolish builders, and unable to finish what they had begun.
