'Severe' in the Bible

Now the battle was very severe that day; Abner and the men of Israel were overcome by David's soldiers.

The men of Israel replied to the men of Judah, "We have ten shares in the king, and we have a greater claim on David than you do! Why do you want to curse us? Weren't we the first to suggest bringing back our king?" But the comments of the men of Judah were more severe than those of the men of Israel.
