Exodus 14:15 And the LORD said unto Moses, Wherefore criest thou unto me? speak unto the children of Israel, that they go forward:
Joshua 7:10-13 And the LORD said unto Joshua, Get thee up; wherefore liest thou thus upon thy face? 11 Israel hath sinned, and they have also transgressed my covenant which I commanded them: for they have even taken of the accursed thing, and have also stolen, and dissembled also, and they have put it even among their own stuff. 12 Therefore the children of Israel could not stand before their enemies, but turned their backs before their enemies, because they were accursed: neither will I be with you any more, except ye destroy the accursed from among you. 13 Up, sanctify the people, and say, Sanctify yourselves against to morrow: for thus saith the LORD God of Israel, There is an accursed thing in the midst of thee, O Israel: thou canst not stand before thine enemies, until ye take away the accursed thing from among you.
