Luke 19:9

This day. Probably spoken with reference to the decision reflected by the confession and promise of Zacchaeus (v. 8), in view of the transformation that had taken place in his life.

This house. Members of Zacchaeus’ household benefited by the decision he had made.

He also. See ch. 13:16. Jewish society had stricken Zacchaeus out of the book of respectability. It had branded him a “sinner” (see ch. 19:7), and therefore ineligible for the rewards the Jews considered automatically came to all literal descendants of father Abraham. In language all could understand, Jesus now reads him into the book of divine favor. For the Jewish concept of the importance and value of literal descent from Abraham see on Matt. 3:9; John 8:39.
