'Lo' in the Bible

Sing and rejoice, O daughter of Zion: for, lo, I come, and I will dwell in the midst of thee, saith the LORD.

For I will no more pity the inhabitants of the land, saith the LORD: but, lo, I will deliver the men every one into his neighbour's hand, and into the hand of his king: and they shall smite the land, and out of their hand I will not deliver them.

For, lo, I will raise up a shepherd in the land, which shall not visit those that be cut off, neither shall seek the young one, nor heal that that is broken, nor feed that that standeth still: but he shall eat the flesh of the fat, and tear their claws in pieces.
