Daniel 1:3 In-Context
In the third year of the reign of Jehoiakim king of Judah, Nebuchadnezzar king of Babylon came to Jerusalem and besieged it.
And the Lord delivered Jehoiakim king of Judah into his hand, along with some of the articles from the temple of God. These he carried off to the temple of his god in Babylonia and put in the treasure house of his god.
Then the king ordered Ashpenaz, chief of his court officials, to bring into the king’s service some of the Israelites from the royal family and the nobility—
young men without any physical defect, handsome, showing aptitude for every kind of learning, well informed, quick to understand, and qualified to serve in the king’s palace. He was to teach them the language and literature of the Babylonians.
The king assigned them a daily amount of food and wine from the king’s table. They were to be trained for three years, and after that they were to enter the king’s service.
