'Aware' in the Bible

The lord of that servant shall come in a day when he looketh not for him, and in an hour that he is not aware of,

Woe unto you, scribes and Pharisees, hypocrites! for ye are as graves which appear not, and the men that walk over them are not aware of them.

The lord of that servant will come in a day when he looketh not for him, and at an hour when he is not aware, and will cut him in sunder, and will appoint him his portion with the unbelievers.
