“If Jews were required to sell all they had and give all the proceeds to the poor (Luke 18:22), why was Joseph rich (Matt. 27:57), and why did Zacchaeus only give half (Luke 19:8)?”
They weren’t required to sell all until Pentecost (Acts 2:44,45). That’s when Barnabas did it (4:32-37). One of the reasons he was singled out as having done so may be to let us know when they did it. — Pastor Ricky Kurth
