Exposition of the Old and New Testament, by John Gill, [1746-63], at sacred-texts.com
2 Chronicles 18:1
ch2 18:1Now Jehoshaphat had riches and honour in abundance,.... Still more and more, see Ch2 17:5, and which moved Ahab to desire friendship and affinity with him, to which Jehoshaphat agreed:
and joined affinity with Ahab; king of Israel, married his son Joram to Athaliah, a daughter of Ahab by Jezebel of Zidon; which marriage proved of bad consequence to Jehoshaphat and his family.
2 Chronicles 18:2
ch2 18:2And after certain years,.... Two years, according to the Syriac and Arabic versions, or in the third year after the affinity was contracted, see Kg1 22:2,
he went down to Ahab to Samaria; to pay him a visit upon the alliance, civil and matrimonial, contracted between them:
and Ahab killed sheep and oxen for him in abundance, and for the people that he had with him; entertained him and his retinue in a very grand and liberal manner:
and persuaded him to go up with him to Ramothgilead; from hence, to the end of the chapter, it is the same with Kg1 22:4.
