'Perennial' in the Bible

And Moses stretcheth out his hand towards the sea, and the sea turneth back, at the turning of the morning, to its perennial flow, and the Egyptians are fleeing at its coming, and Jehovah shaketh off the Egyptians in the midst of the sea,

Thou hast cleaved a fountain and a stream, Thou hast dried up perennial flowings.

And roll on as waters doth judgment, And righteousness as a perennial stream.
