'Behold' in the Bible

So all Israel was enrolled in genealogy. And behold, they were written in the book of the kings of Israel. And Judah was taken away to Babylon on account of their sin.

Behold, a son shall be born to you; he himself will be a man of rest, and I will give rest to him from all his enemies all around, for his name will be Solomon, and peace and quietness I will give to Israel in his days.

And behold, the working groups of the priests and the Levites for all the service of the house of God; and with you in all the work for all [those] willing with the skill for every service, and the commanders and all the people for all your commands."
