Psalm 127:1

Unless the Lord builds the house,
They labor in vain who build it;
Unless the Lord guards the city,
The watchman stays awake in vain.

2 Samuel 18:33

Then the king was deeply moved, and went up to the chamber over the gate, and wept. And as he went, he said thus: “O my son Absalom—my son, my son Absalom—if only I had died in your place! O Absalom my son, my son!”

Psalm 127:5

Happy is the man who has his quiver full of them;
They shall not be ashamed,
But shall speak with their enemies in the gate.
