Therefore hath the Lord watched: this notes,
1. God's taking notice of all their ways, even while men sleep in carnal security, and dream of no danger.
2. God's watching here notes the fit ways that he always takes to punish sinners.
3. It notes his haste in executing judgment duly and seasonably, when it makes most for the honour of his justice.
4. That he may, like a careful watchman, not suffer any to escape his hands.
