'Bragging' in the Bible

Zebul said to him, "Where now are your bragging words, 'Who is Abimelech that we should serve him?' Are these not the men you insulted? Go out now and fight them!"

When he finally finished bragging, he discarded the jawbone and named that place "Jawbone Heights."

He keeps bragging: "I've done it by the strength of my hand, and by my wisdom, because I'm so clever. I removed the boundaries of nations, and plundered their treasures; like a bull I brought down those who sat on thrones.
