Psalm 127
Nisi Dominus
EXCEPT the Lord build the house : their labour is but lost that build it.
2 Except the Lord keep the city : the watchman waketh but in vain.
3 It is but lost labour that ye haste to rise up early, and so late take rest, and eat the bread of carefulness : for so he giveth his beloved sleep.
4 Lo, children and the fruit of the womb : are an heritage and gift that cometh of the Lord.
5 Like as the arrows in the hand of the giant : even so are the young children.
6 Happy is the man that hath his quiver full of them : they shall not be ashamed when they speak with their enemies in the gate.
