2 Kings 1:1
INTRODUCTION TO THE SECOND BOOK OF KINGS COMMONLY CALLED THE FOURTH BOOK OF THE KINGS
This, and the preceding book, are properly but one book divided into two parts, because of the size of it, as the book of Samuel; it is a continuation of the history of the kings of Israel and Judah; and for a further account of it the reader is referred to the title of the preceding book.
INTRODUCTION TO 2 KINGS 1
This chapter begins with the rebellion of Moab against Israel, 2Ki 1:1, relates a fall of the king of Israel in his house, which brought on him a sickness, about which he sent messengers to inquire of the god of Ekron, who were stopped by Elijah, and bid to return, as they did; and upon the king's examination of them about the cause of their return, he perceived it was Elijah that forbad them, 2Ki 1:2, upon which the king sent to him two captains, with fifty men each, one after another, to bring him to him, but fire came down from heaven and consumed them, 2Ki 1:9, but a third with fifty men sent to him were spared, and he is bid to go along with them with a message to the king, as he did, 2Ki 1:13 and the chapter is closed with the death of Ahaziah, 2Ki 1:17.
Ver. 1. Then Moab rebelled against Israel after the death of Ahab. Which had been in subjection to them from the times of David, 2Sa 8:2 refusing to pay a tribute as they had done; taking advantage of Ahab's ill success with the king of Syria, and of his death, and the condition and circumstances of his successor.
