Albert Barnes Commentary 2 Samuel 15:2

"And Absalom rose up early, and stood beside the way of the gate: and it was so, that, when any man had a suit which should come to the king for judgment, then Absalom called unto him, and said, Of what city art thou? And he said, Thy servant is of one of the tribes of Israel." — 2 Samuel 15:2 (ASV)

Beside the gate — See the note on Ruth 4:1.
