'Look' in the Bible

Naomi said, “Look, your sister-in-law has gone back to her people and to her god. Follow your sister-in-law.”

And look, Boaz came from Bethlehem and said to the reapers, "[May] Yahweh [be] with you." And they said to him, "[May] Yahweh bless you."

Isn't Boaz one of our close relatives? You've been associating with his women servants lately. Look, he'll be winnowing barley at the threshing floor tonight.

And Boaz had gone up [to] the [city] gate and sat there. And look, the redeemer of whom Boaz had spoken [was] passing by. And he said, "Come over here to sit, {friend}." And he came over and sat.
