'Behold' in the Bible

Then she said, “Behold, your sister-in-law has gone back to her people and her gods; return after your sister-in-law.”

Now behold, Boaz came from Bethlehem and said to the reapers, “May the Lord be with you.” And they said to him, “May the Lord bless you.”

Now is not Boaz our kinsman, with whose maids you were? Behold, he winnows barley at the threshing floor tonight.

It happened in the middle of the night that the man was startled and bent forward; and behold, a woman was lying at his feet.

Now Boaz went up to the gate and sat down there, and behold, the close relative of whom Boaz spoke was passing by, so he said, “Turn aside, friend, sit down here.” And he turned aside and sat down.
