'Presumed' in the Bible

Then you answered and said to me, "We have sinned against Yahweh, we will go up and fight, according to all that Yahweh our God commanded us." Every man of you put on his weapons of war, and presumed to go up into the hill country.

whenever a prophet speaks in my name and the prediction is not fulfilled, then I have not spoken it; the prophet has presumed to speak it, so you need not fear him."
