'Suspect' in the Bible

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.

I ask that when I do come I will not be driven to the boldness that I intend to show toward those few who regard us as if we walked according to the flesh [like men without the Spirit].

So remember and take to heart the lessons you have received and heard. Keep and obey them, and repent [change your sinful way of thinking, and demonstrate your repentance with new behavior that proves a conscious decision to turn away from sin]. So then, if you do not wake up, I will come like a thief, and you will not know at what hour I will come to you.
