That those who obeyed God’s commandments would be blessed signifies that we, the New Testament believers, are blessed by walking according to the Spirit (Rom. 8:4), with six issues:
1) Rains in their season (v. 4a) signify that the Spirit, typified by rain (Deut. 11:14; Jer. 5:24; Joel 2:23), is given to the church or to the individual believers in due time.
2) The land yielding its rich produce that the people may eat the new food always and dwell securely in the land (vv. 4-5, 10) signifies that we dwell in Christ as our good land and enjoy the riches of Christ for our satisfaction and security (Eph. 3:8; Col. 1:12).
3) Peace being given in the land without threats, wild beasts, and the sword (v. 6) signifies that the church is normally in a peaceful situation, having no “wild beasts” (cf. Acts 20:29) or fightings among the saints (James 4:1).
4) Chasing the enemies, five chasing a hundred and a hundred chasing ten thousand (vv. 7-8), signifies that the church will chase the enemies (Eph. 6:12) in the coordination of the Body.
5) Fruitfulness in multiplication (v. 9) signifies that the church will be fruitful and multiply (John 15:8, 16).
6) God setting His tabernacle among the people (v. 11) signifies that God’s dwelling will be built up in the church for God’s delight that He may dwell among His people (cf. 2 Cor. 6:16-18).
