1Unless the LORD builds the house, those who build it labor in vain. Unless the LORD watches over the city, the watchman stays awake in vain. (诗121:4)2It is in vain that you rise up early and go late to rest, eating the bread of anxious toil; for he gives to his beloved sleep. (创3:17; 创3:19; 诗60:5; 可4:26; 可4:27)3Behold, children are a heritage from the LORD, the fruit of the womb a reward. (创33:5; 申28:4; 诗132:11)4Like arrows in the hand of a warrior are the children[1] of one’s youth. (诗120:4)5Blessed is the man who fills his quiver with them! He shall not be put to shame when he speaks with his enemies in the gate.[2] (伯5:4)
