'Dismissed' in the Bible

And Abner said to David, "Let me get up and go and gather all of Israel to my lord the king, that they may {make a covenant} with you so you can reign over all which your soul desires." So David dismissed Abner, and he left in peace.

And look, the servants of David and Joab came from the raid, and they brought much plunder with them. But Abner was not with David at Hebron, for he had dismissed him, and he had gone in peace.

Then Joab came to the king and said, "What have you done? Abner came here to you? Why have you dismissed him that he {actually went away}?
