'Boasting' in the Bible

May the Lord cut off all flattering lips,The tongue that speaks great things [in boasting];

In this way I will punish the world for its evilAnd the wicked for their wickedness [their sin, their injustice, their wrongdoing];I will also put an end to the arrogance of the proudAnd will abase the arrogance of the tyrant.

We have heard of the pride of Moab, an excessive pride—Even of his arrogance, his conceit, his rage,His untruthful boasting.

Frustrating the signs and confounding the omens of boasters (false prophets),Making fools out of fortune-tellers,Counteracting the wiseAnd making their knowledge ridiculous,

Hear this, I am against those who have prophesied false and made-up dreams,” says the Lord, “and have told them and have made My people err and go astray by their lies and by their reckless boasting; yet I did not send them or command them nor do they benefit and enhance [the life of] these people in the slightest way,” says the Lord.
