'Nightly' in the Bible

A Song, a Psalm, by sons of Korah, to the Overseer, 'Concerning the Sickness of Afflictions.' -- An instruction, by Heman the Ezrahite. O Jehovah, God of my salvation, Daily I have cried, nightly before Thee,

'Thus said Jehovah: If ye do break My covenant of the day, And My covenant of the night, So that they are not daily and nightly in their season,

Thus said Jehovah: If My covenant is not daily and nightly, The statutes of heaven and earth I have not appointed --

Cried hath their heart unto the Lord; O wall of the daughter of Zion, Cause to go down as a stream tears daily and nightly, Give not rest to thyself, Let not the daughter of thine eye stand still.
