'Day' in the Bible

Good is Jehovah for a strong place in a day of distress. And He knoweth those trusting in Him.

The shield of his mighty ones is become red, Men of might are in scarlet, With fiery torches is the chariot in a day of his preparation, And the firs have been caused to tremble.

Thy crowned ones are as a locust, And thy princes as great grasshoppers, That encamp in hedges in a day of cold, The sun hath risen, and it doth flee away, And not known is its place where they are.
