'Behold' in the Bible

She said, "Behold, your sister-in-law has gone back to her people, and to her god. Follow your sister-in-law."

Behold, Boaz came from Bethlehem, and said to the reapers, "Yahweh be with you." They answered him, "Yahweh bless you."

Now isn't Boaz our kinsman, with whose maidens you were? Behold, he winnows barley tonight in the threshing floor.

It happened at midnight, that the man was startled and turned himself; and behold, a woman lay at his feet.

Now Boaz went up to the gate, and sat down there. Behold, the near kinsman of whom Boaz spoke came by; to whom he said, "Come over here, friend, and sit down!" He turned aside, and sat down.
