'Slowly' in the Bible

"Son of Man, what's this proverb you have concerning Israel's land that says, "The days pass slowly and every vision ends in nothing.'?

“Then I will make their waters quiet and clear;I will make their rivers run [slowly and smoothly] like oil,”Says the Lord God.

And he took me out by the north doorway, and made me go round to the outside of the doorway looking to the east; and I saw waters running slowly out on the south side.
