Jeroboam II was the King of Israel during the time of Prophet Amos. Although he did evil in the eyes of the Lord and Amos prophesied that he would die by sword, God still blessed King Jeroboam II with a very successful reign which lasted for 41years.
And since the LORD had not said he would blot out the name of Israel from under heaven, he saved them by the hand of Jeroboam son of Jehoash. 2 KINGS 14:27
When we see people who seem to have everything in life lots of money, a great career, good health it’s tempting to think that God must somehow like them better than us. But the story of King Jeroboam II should show us that material blessings do not automatically equal approval from God.
Like the king of Israel before him with the same name, King Jeroboam II of Israel did evil in the eyes of the Lord. Yet his reign appears to have been extremely successful in every other way. He reigned for a lengthy forty-one years, and his domain expanded considerably under his rule, virtually doubling in size (2 Kings 14). The Bible doesn’t say anything about Jeroboam suffering any great difficulties during his reign (although the prophet Amos apparently prophesied that he would die by the sword — see Amos 7).
So does this mean that God actually approved of Jeroboam? Or that He didn’t really care whether he was evil or not? Not at all. Rather, the Lord allowed these good things to come because of love for His people, not Jeroboam’s behavior (2 Kings 14:26–27). As with ancient Israel, often what appears to be God’s tolerance of evil is actually a demonstration of His mercy (2 Peter 3:9)
From a historical perspective, Jeroboam was able to expand his territory thanks to the Assyrian Empire, which had attacked and weakened Aram to the north but then retreated to attend to other matters for a time. Years later the Assyrians would return and capture Israel, exiling the people to faraway places.
