'Behold' in the Bible

It was then that Boaz came back from Bethlehem and said to the reapers, “The Lord be with you!” And they answered him, “The Lord bless you!”

In the middle of the night the man was startled and he turned over, and found a woman lying at his feet.

Then Boaz went up to the city gate [where business and legal matters were settled] and sat down, and then the close relative (redeemer) of whom Boaz had spoken came by. He said to him, “Come over here, friend, and sit down.” So he came and sat down.
