C. F. Keil and Franz Delitzsch on 2 Kings 13:7

2Ki 13:7 “For (כּי) he had not left,” etc., furnishes the ground for 2Ki 13:5 : God gave them a saviour, ... although they did not desist from the sin of Jeroboam, ... for Israel had been brought to the last extremity; He (Jehovah) had left to Jehoahaz people (עם, people of war), only fifty horsemen, etc. For החטי instead of החטיא (2Ki 13:6), see at 1Ki 21:21. The suffix בּהּ in 2Ki 13:6 refers to הטּאת, just as that in ממּנּה in 2Ki 13:2 (see at 2Ki 3:3). “And even the Asherah was (still) standing at Samaria,” probably from the time of Ahab downwards (1Ki 16:33), since Jehu is not said to have destroyed it (2Ki 10:26.). וגו וישׂמם “and had made them like dust for trampling upon,” - an expression denoting utter destruction.
