'Keep' in the Bible

The earth is troubled before them and the heavens are shaking: the sun and the moon have become dark, and the stars keep back their shining:

“Even now,” says the Lord,“Turn and come to Me with all your heart [in genuine repentance],With fasting and weeping and mourning [until every barrier is removed and the broken fellowship is restored];

The sun and the moon have become dark, and the stars keep back their shining.
