'Sons' in the Bible

Hear, O children, the instruction of a father,And pay attention [and be willing to learn] so that you may gain understanding and intelligent discernment.

Now then, my sons, listen to meAnd do not depart from (forget) the words of my mouth.

Now therefore, my sons, listen to me,And pay attention to the words of my mouth.

“To you, O men, I call,And my voice is directed to the sons of men.

Rejoicing in the world, His inhabited earth,And having my delight in the sons of men.

“Now therefore, O sons, listen to me,For blessed [happy, prosperous, to be admired] are they who keep my ways.
