'Works' in the Bible

Their works will not let them come back to their God, for a false spirit is in them and they have no knowledge of the Lord.

And Ephraim said, Now I have got wealth and much property; in all my works no sin may be seen in me.

And now they sin more and more,And make for themselves molten images,Idols skillfully made from their silver [as it pleased them],All of them the work of the craftsmen.They say of these [very works of their hands], “Let those who sacrifice kiss and show respect to the calves [as if they were living gods]!”
