'Drifting' in the Bible

So Jesus said to them, “The Light is among you [only] a little while longer. Walk while you have the Light [keep on living by it], so that darkness will not overtake you. He who walks in the darkness does not know where he is going [he is drifting aimlessly].

When the fourteenth night came, we were drifting in the Adriatic Sea, and in the middle of the night the sailors thought they were approaching land.
