Ibn Ezra
לא The true meaning of the word is to Him;15I. E. usually follows the Keri, that is, the reading recommended by the Massorah; לו to him is here the Keri, לׂא not, the Ketib. and לא צר (lit., Unto Him was trouble), he was afflicted, has the same meaning as And His soul was grieved (Jud. 10:16). It is a figurative expression. He was, as it were, in distress, therefore He hastened to deliver them.
Rashi
He did not trouble [them] He did not trouble them according to their deeds, that they deserved to suffer, for the angel of His presencei.e., Michael the prince of the Presence, of those who minister before Him saved them always as an agent of the Omnipresent.
