They are nothing 

Isaiah 42:17

17 They shall be turned back, they shall be greatly ashamed, that trust in graven images, that say to the molten images, Ye are our gods.

Isaiah 41:29 

29 Behold, they are all vanity; their works are nothing: their molten images are wind and confusion.

Isaiah 41:29 in all English translations

Psalm 127

127 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.
