'Lo' in the Bible

Therefore, lo, I am hedging up thy way with thorns, And I have made for her a wall, And her paths she doth not find.

Therefore, lo, I am enticing her, And have caused her to go to the wilderness, And I have spoken unto her heart,

For, lo, they have gone because of destruction, Egypt gathereth them, Moph burieth them, The desirable things of their silver, Nettles possess them -- a thorn is in their tents.
