'Add' in the Bible

Thus said Jehovah of Hosts, God of Israel, Your burnt-offerings add to your sacrifices, And eat ye flesh.

And they have come in, And have sung in the high place of Zion, And flowed unto the goodness of Jehovah, For wheat, and for new wine, and for oil, And for the young of the flock and herd, And their soul hath been as a watered garden, And they add not to grieve any more.
