'Hard' in the Bible

and the battle is very hard on that day, and Abner is smitten, and the men of Israel, before the servants of David.

and I to-day am tender, and an anointed king: and these men, sons of Zeruiah, are too hard for me; Jehovah doth recompense to the doer of the evil according to his evil.'

And Amnon hath distress -- even to become sick, because of Tamar his sister, for she is a virgin, and it is hard in the eyes of Amnon to do anything to her.
