Some claim that, since these specific instructions are given in reference to animals offered to God, the principle of giving one's best to the Master does not apply to vegetable or grain offerings! Does that mean we may give God any old vegetation we happen to have lying around? As living sacrifices (Romans 12:1-2), are we free to give God any old thing, and He must accept it or else? Does He not deserve the best we have?
A holy people must give holy offerings! A holy offering is one given according to the details that God lays down. Jesus gives a practical application of this principle in Matthew 5:23-24: "Therefore if you bring your gift to the altar, and there remember that your brother has something against you, leave your gift there before the altar, and go your way. First be reconciled to your brother, and then come and offer your gift."
He is essentially saying, "First things first." If a reconciliation does not take place, God has no obligation to accept the offering. It has been made based on a corrupt relationship with a brother, making the offering unacceptable. Likewise, God has no obligation to accept a defective, corrupted animal or unqualified grain offered before Him.
Furthermore, the principle of holiness comes to the fore in an additional way, for God plainly stipulates in Leviticus 22:25 that nothing is to be offered to Him from a foreigner's hand because the foreigner's corruption is in them. The uncleanness from the foreigner's idolatries is in the thing offered. The foreigner is not a holy, sanctified, or set-apart person.
In the case of Joshua 5:10-11, the Israelites clearly would have had to offer produce from the foreigner's hand—if they offered anything, which they did not—because that was all they would have had to offer. Having just come from the wilderness, they had no harvest of a crop they had sown, as Exodus 23:16 demands.
