God has blessed God’s people, and God will fulfill that promise, for God is “not a human being.”
The BalaamA soothsayer who blessed Israel at the end of the wilderness wanderings. More story sets up the conflict between the religious and military powers of the ancient world and the seemingly simple word of blessingBlessing is the asking for or the giving of God's favor. Isaac was tricked into blessing Jacob instead of his firstborn Esau. At the Last Supper Jesus offered a blessing over bread and wine. To be blessed is to be favored by God. More in the mouth of God. Neither the military might of Moab nor the terrible curses and divinations of ancient religion can thwart God’s promise to bless God’s people. The blessing of God will prove stronger than all contenders (see Numbers 23:23). Here is an early form of the ongoing biblical notion of God’s strength through weakness, that God’s word of promise is stronger and more trustworthy than all the powers of the world and the forces of human religion.
The rationale given here for God’s fidelity to the promise is that “God is not a human being,” not “a mortal.” Thus, God will not lie (as a human might!). In Hebrew, God is neither an ‘ish (a man, a male, a husband, a human) nor a ben-‘adamThe first man God created. More (a “son of Adam,” a member of the human species). That God is not a male human being is seen as good news. The Bible knows that no “likeness”–not that “of male or female”–can depict or capture God. God is rather present, as God chooses to be, in God’s word (Deuteronomy 4:12, 15-18); here, in Balaam’s oracleAn oracle is a divine utterance of guidance, promise, or judgment delivered to humans through an intermediary (who is often also called an oracle). In the Bible oracles are given by Balaam (in the book of Numbers) and by David (in 2 Samuel). A number... More of blessing, it is that word of divine promise that will determine Israel’s future. HoseaProphet to the northern kingdom who married a prostitute to show God's relationship to a faithless Israel More, too, knew that God was “no mortal” (that is, not an ‘ish), also recognizing that to be good news, for it was a mark of God’s gracious holiness that would not subject Israel to wrath.
