PSA 127:1

1 The song of degrees of Solomon. No but the Lord build the house; they that built it have travailed in vain. No but the Lord keepeth the city; he waketh in vain that keepeth it./But if the Lord build the house; they that built it have travailed in vain. But (if) the Lord keepeth the city; he waketh in vain that keepeth it. (A song of Solomon for steps of ascending. Unless the Lord build the house; those who have built it, have laboured in vain. Unless the Lord guardeth the city; he who standeth watch, guardeth in vain.)
