This offering was something in addition to the tithes (Deut. 14:22-27). Like the tithes, a portion of the first of all the fruit was to be offered to God and enjoyed with God in the place which God would choose. See note Deut. 12:5¹.

Or, wandering.

See note Deut. 14:28¹.

Or, the habitation of Your holiness.

This indicates that if we, for the sake of God, take care of the needy ones in the church, God will surely bless our labor and undertakings. This blessing will be a return to us from God (cf. 2 Cor. 9:6). Apparently we are giving; actually we are receiving. Nevertheless, to give is much more blessed than to receive (Acts 20:35).

In this section of the rehearsal of the law (14:1—26:19) five governing principles of our behavior are implied:
1) toward God, to be sanctified and fearing;
2) toward oneself, to be righteous and pure; (3) toward others, to be kind and generous;
4) toward animals, to be sparing and sympathetic;
5) toward the devil, to be rejecting and separated.
All God’s people should practice these principles by the divine life.
