'Knocketh' in the Bible

for every one that asketh receiveth; and he that seeketh findeth; and to him that knocketh it shall be opened.

For every one that asketh receiveth; and he that seeketh findeth; and to him that knocketh it shall be opened.

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.
