'Swim' in the Bible

I am weary with my sighing;Every night I make my bed swim,I dissolve my couch with my tears.

And he will spread out his hands in the middle of itAs a swimmer spreads out his hands to swim,But the Lord will lay low his pride together with the trickery of his hands.

Again he measured a thousand; and it was a river that I could not ford, for the water had risen, enough water to swim in, a river that could not be forded.
