Then you will be like servants waiting for their master to return from the wedding banquet, so that when he comes and knocks, they can open the door for him at once.
KJV
And ye yourselves like unto men that wait for their lord, when he will return from the wedding; that when he cometh and knocketh, they may open unto him immediately.
ASV
and be ye yourselves like unto men looking for their lord, when he shall return from the marriage feast; that, when he cometh and knocketh, they may straightway open unto him.
