'Sons' in the Bible

Then Arioch brought in Daniel before the king in haste, and said thus unto him: I have found a man of the sons of the captivity of Judah that will make known unto the king the interpretation.

and he was driven from the sons of men, and his heart was made like the beasts, and his dwelling was with the wild asses; they fed him with grass like oxen, and his body was bathed with the dew of heaven; till he knew that the Most High God ruleth over the kingdom of men, and that he appointeth over it whomsoever he will.

And behold, one after the likeness of the sons of men touched my lips; and I opened my mouth and spoke, and said unto him that stood before me, My lord, by reason of the vision my pains are turned upon me, and I retain no strength.

And his sons shall be stirred up, and shall assemble a multitude of great forces; and one shall certainly come, and overflow, and pass through; and he shall return and carry the war even to his fortress.
