Psalm 126:5 KJV
They that sow in tears shall reap in joy.
Psalm 126:1-4,6 KJV
When the Lord turned again the captivity of Zion, we were like them that dream. [2] Then was our mouth filled with laughter, and our tongue with singing: then said they among the heathen, The Lord hath done great things for them. [3] The Lord hath done great things for us; whereof we are glad. [4] Turn again our captivity, O Lord, as the streams in the south. [6] He that goeth forth and weepeth, bearing precious seed, shall doubtless come again with rejoicing, bringing his sheaves with him.
Psalm 127:1-5 KJV
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. [2] It is vain for you to rise up early, to sit up late, to eat the bread of sorrows: for so he giveth his beloved sleep. [3] Lo, children are an heritage of the Lord : and the fruit of the womb is his reward. [4] As arrows are in the hand of a mighty man; so are children of the youth. [5] Happy is the man that hath his quiver full of them: they shall not be ashamed, but they shall speak with the enemies in the gate.
