'Trained' in the Bible

So Moses was trained in all the wisdom of the Egyptians and was powerful in his words and deeds.

This man had been trained in the way of the Lord; and burning in spirit, he gave himself up to teaching the facts about Jesus, though he had knowledge only of John's baptism:

I am a Jew of Tarsus in Cilicia by birth, but I had my education in this town at the feet of Gamaliel, being trained in the keeping of every detail of the law of our fathers; given up to the cause of God with all my heart, as you are today.
