'Strict' in the Bible

“So be alert [give strict attention, be cautious and active in faith], for you do not know which day [whether near or far] your Lord is coming.

Therefore, be on the alert [be prepared and ready], for you do not know the day nor the hour [when the Son of Man will come].

Keep actively watching and praying that you may not come into temptation; the spirit is willing, but the body is weak.”

Therefore, be continually on the alert—for you do not know when the master of the house is coming, whether in the evening, or at midnight, or when the rooster crows, or in the morning—

What I say to you I say to everyone, ‘Be on the alert [stay awake and be continually cautious]!’”

He, having received such a [strict] command, threw them into the inner prison (dungeon) and fastened their feet in the stocks [in an agonizing position].
