KJV:
Children in whom was no blemish, but well favoured, and skilful in all wisdom, and cunning in knowledge, and understanding science, and such as had ability in them to stand in the king's palace, and whom they might teach the learning and the tongue of the Chaldeans.
NKJV:
young men in whom there was no blemish, but good-looking, gifted in all wisdom, possessing knowledge and quick to understand, who had ability to serve in the king's palace, and whom they might teach the language and literature of the Chaldeans.
NIV:
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.
Interpretation:
Nebuchadnezzar selected young men with natural abilities. They were intelligent, well-educated, and physically impressive. The king wanted those who showed aptitude for learning. The verse shows that people have natural abilities from birth. However, natural ability alone is not enough. These young men would face choices about using their abilities for God or for the world. Having ability does not guarantee using it wisely. True success comes when we use our abilities to honor God.
