In order to cheer the miserable Jews by some consolation, God said, in what we considered yesterday, that the wantonness of Moab was known to him; he now adds, that he would visit with punishment the reproaches which had been mentioned. For it would have availed them but little that their wrongs had been observed by God, if no punishment had been prepared. Hence the Prophet reminds them that God is no idle spectator, who only observes what takes place in the world; but that there is a reward laid up for all the ungodly. And these verses are to be taken in connection, that the faithful may know that their wrongs are not unknown to God, and also that he will be their defender. But that the Jews might have a more sure confidence that God would be their deliverer, he interposes an oath. God at the same time shows that he is really touched when he sees his people so cruelly and immoderately harassed, when the ungodly seem to think that an unbridled license is permitted them. God therefore shows here, that not only the salvation of his people is an object of his care, but that he undertakes their cause as though his anger was kindled; not that passions belong to him but such a form of speaking is adopted in order to express what the faithful could never otherwise conceive an idea of, that is, to express the unspeakable love of God towards them, and his care for them.
