What does Isaiah 19:19 mean?
In a distant future, Egypt will turn to the Lord God of Israel (Isaiah 19:18). After being filled with dread over what the Lord could do to them, the people of Egypt will repent and swear allegiance to the Lord. The God of Israel will become the God of Egypt (Isaiah 19:16–17). This description must be pointing toward the kingdom of the Messiah, who will rule over all the nations from His throne in Jerusalem (Isaiah 2:1–5; Revelation 20:1–4). Egypt will be one of those nations. The people will abandon their former gods and even build an altar and a pillar to the Lord in their land. In other words, their commitment to Israel's God, in the form of the Messiah, will be open and public for all the world to see.Once more, Isaiah wants Judah to hold on to courageous trust in the Lord during their difficult season. They are to look forward to the day when all the earth will share their trust in the Messiah King of Israel.
