'Cannot' in the Bible

The king and his men went to Jerusalem, to the Jebusites, the inhabitants of the land. They said to David, "You will not come here, for even the blind and the lame can turn you back, saying, 'David cannot come here.'"

David had said, "On that day {when we attack the Jebusites}, one must attack the lame and the blind, [those] who hate the soul of David, by [means of] the water supply." For thus the blind and the lame would say, "He cannot come into the house."

But now he [is] dead. Why [should I be] fasting? [Am] I able to return him again? I [am] going to him, but he cannot return to me."

For {we must certainly die}, and [we are] as the waters spilled to the ground which cannot be gathered. God will not take a life but devises plans for a banished person not to be cast out from him.

The king asked, "[Was] the hand of Joab with you in all of this?" The woman answered and said, "{As your soul lives}, my lord the king, surely [one cannot] go to the right or to the left from all that my lord the king has spoken. Yes, your servant Joab himself commanded me, and he put all of these words in the mouth of your servant.

But evil persons [are] like thorns cast aside; all of them, because they cannot be picked up in the hand.
