'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 are gone because of destruction: Egypt shall gather them up, Memphis shall bury them: the pleasant places for their silver, nettles shall possess them: thorns shall be in their tabernacles.
