Beware!

Be sure of this: if the master of the house
had known the hour of night when the thief was coming,
he would have stayed awake
and not let his house be broken into.
So too, you also must be prepared,
for at an hour you do not expect, the Son of Man will come.

Matthew 24:37-44

Beware! The thief is coming,
though no one knows the hour
when David's key is turning
and Jesse's root shall flow'r.
Then all your strong defenses
will crumble to the ground:
He'll come with recompenses
while mountains tumble down.

Be watchful, and be ready—
Do not, dare not to sleep!
His coming, long awaited,
th'appointed time shall keep.
Prepare yourself for testing;
stand firmly in the fight:
The plow must be your weapon,
your armor made of light.

Behold, this is the moment—
shall it e'er come again?—
the thief is on your doorstep
and knocks to be let in.
Make ready to receive him;
prepare a level way.
Get up and let the thief in:
At your house he must stay.
