'Boasting' in the Bible

Then Zebul said to him, “Where is your boasting now with which you said, ‘Who is Abimelech that we should serve him?’ Is this not the people whom you despised? Go out now and fight with them!”

You said, ‘Behold, you have defeated Edom.’ And your heart has become proud in boasting. Now stay at home; for why should you provoke trouble so that you, even you, would fall and Judah with you?”

Behold, I am against those who have prophesied false dreams,” declares the Lord, “and related them and led My people astray by their falsehoods and reckless boasting; yet I did not send them or command them, nor do they furnish this people the slightest benefit,” declares the Lord.
