'Learned' in the Bible

Now this is the copy of the decree which King Artaxerxes gave to Ezra the priest, the scribe, learned in the words of the commandments of the Lord and His statutes to Israel:

and I came to Jerusalem and learned about the evil that Eliashib had done for Tobiah, by preparing a room for him in the courts of the house of God.

When Mordecai learned all that had been done, he tore his clothes, put on sackcloth and ashes, and went out into the midst of the city and wailed loudly and bitterly.

But they mingled with the nationsAnd learned their practices,

Neither have I learned wisdom,Nor do I have the knowledge of the Holy One.

Then the Lord said,“Because this people draw near with their wordsAnd honor Me with their lip service,But they remove their hearts far from Me,And their reverence for Me consists of tradition learned by rote,

‘When she brought up one of her cubs,He became a lion,And he learned to tear his prey;He devoured men.

‘And he walked about among the lions;He became a young lion,He learned to tear his prey;He devoured men.

He was also driven away from mankind, and his heart was made like that of beasts, and his dwelling place was with the wild donkeys. He was given grass to eat like cattle, and his body was drenched with the dew of heaven until he recognized that the Most High God is ruler over the realm of mankind and that He sets over it whomever He wishes.
