It is significant that Daniel 1:2 says that “the Lord delivered Jehoiakim into his [Nebuchadnezzar’s] hand." This shows us that God is in control of history. It also shows us that God is a holy God who keeps his Word, also when that Word is a word of warning. The broader context shows however that God is also merciful. Alongside the prophetic warnings of exile, there were also promises of salvation beyond the exile. These are fulfilled in Jesus Christ.
Read Daniel 1:1-2
