Numbers 22:38

But Balaam, being still mindful of the warning which he had just received from God, replied, "Lo, I am come unto thee now: have I then any power to speak anything (sc., of my own accord)? "The word which God puts into my mouth, that will I speak." With this reply he sought, at the very outset, to soften down the expectations of Balak, inasmuch as he concluded at once that his coming was a proof of his willingness to curse (Hengstenberg). As a matter of fact, Balaam did not say anything different to the king form what he had explained to his messengers at the very first (cf. Num 22:18). But just as he had not told them the whole truth, but had concealed the fact that Jehovah, his God, had forbidden the journey at first, on the ground that he was not to curse the nation that was blessed (Num 22:12), so he could not address the king in open, unambiguous words.

At this chapter begins the famous story of Balak and Balaam, their attempt to curse Israel, and the baffling of that attempt; God's people are long afterwards told to remember what Balak the king of Moab consulted, and what Balaam the son of Beor answered him, that they might know the righteousness of the Lord, Mic 6:5. In this chapter we have, I. Balak's fear of Israel, and the plot he had to get them cursed (Num 22:1-4). II. The embassy he sent to Balaam, a conjurer, to fetch him for that purpose, and the disappointment he met with in the first embassy (Num 22:5-14). III. Balaam's coming to him upon his second message (Num 22:15-21). IV. The opposition Balaam met with by the way (Num 22:22-35). V. The interview at length between Balak and Balaam (Num 22:36, etc.).

22:38 Balaam’s reply reflected the lesson he had learned in the donkey incident (cp. 22:20, 35).
