'Young' in the Bible

Then Boaz said to his servant who was set over the reapers, "Whose young lady is this?"

Let your eyes be on the field that they reap, and go after them. Haven't I commanded the young men not to touch you? When you are thirsty, go to the vessels, and drink from that which the young men have drawn."

When she had risen up to glean, Boaz commanded his young men, saying, "Let her glean even among the sheaves, and don't reproach her.

Ruth the Moabitess said, "Yes, he said to me, 'You shall stay close to my young men, until they have ended all my harvest.'"

He said, "Blessed are you by Yahweh, my daughter. You have shown more kindness in the latter end than at the beginning, inasmuch as you didn't follow young men, whether poor or rich.

Let your house be like the house of Perez, whom Tamar bore to Judah, of the seed which Yahweh shall give you of this young woman."
