'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].

The fourteenth night had come and we were drifting and being driven about in the Adriatic Sea, when about midnight the sailors began to suspect that they were approaching some land.
