'Lo' in the Bible

And ought not this woman, being a daughter of Abraham, whom Satan had bound, lo, these eighteen years, to have been loosed from this bond on the day of the sabbath?

But he answered and said to his father, Lo, these many years do I serve thee, and I never transgressed a commandment of thine; and yet thou never gavest me a kid, that I might make merry with my friends:

neither shall they say, Lo, here! or, There! for lo, the kingdom of God is within you.

And they shall say to you, Lo, there! Lo, here! go not away, nor follow after them :

And Peter said, Lo, we have left our own, and followed thee.
