sn Balaam is not here making a general confession of sin. What he is admitting to is a procedural mistake. The basic meaning of the word is “to miss the mark.” He now knows he took the wrong way, i.e., in coming to curse Israel.
sn The reference is to Balaam’s way. He is saying that if what he is doing is so perverse, so evil, he will turn around and go home. Of course, it did not appear that he had much of a chance of going forward.
tn The verb is the cohortative from “return”: I will return [me].
