A.T. Robertson Commentary Acts 21:17

"And when we were come to Jerusalem, the brethren received us gladly." — Acts 21:17 (ASV)

When we were come (γενομενων ημων). Genitive absolute again, "we having come."

Received (απεδεξαντο). Αποδεχομα, to receive from. This old compound only in Luke in the N.T.

Gladly (ασμενως). Old adverb ησμενως from ηδομα, to be pleased. Here only in the N.T. Perhaps this first glad welcome was from Paul's personal friends in Jerusalem.
