Except the LORD build the house, they labour in vain that build it: except the LORD keep the city, the watchman waketh but in vain.
Psalms 127:1

Whosoever cometh to me, and heareth my sayings, and doeth them, I will shew you to whom he is like: He is like a man which built as house, and digged deep, and laid the foundation on a rock: and when the flood arose, the stream beat vehemently upon that house, and could not shake it: for it was founded upon a rock.
Luke 6:47-48
