'Day' in the Bible

The LORD is good, a strong hold in the day of trouble; and he knoweth them that trust in him.

Like tangled thorn branches [gathered for fuel],And like those drowned in drunkenness,The people of Nineveh are consumed [through fire]Like stubble completely withered and dry [in the day of the Lord’s wrath].

The shield of his mighty men is made red, the valiant men are in scarlet: the chariots shall be with flaming torches in the day of his preparation, and the fir trees shall be terribly shaken.

Nineveh hath been like a pool of water, since the day she existed, yet they flee away. ... Stand! Stand! But none looketh back.

Thy crowned are as the locusts, and thy captains as the great grasshoppers, which camp in the hedges in the cold day, but when the sun ariseth they flee away, and their place is not known where they are.
