From Strong’s Concordance:
Hebrew:
Result of search for "2005":
2005 hen hane a primitive particle; lo!; also (as expressing surprise) if:–behold, if, lo, though.
Greek:
Result of search for "2005":
2005. epiteleo ep-ee-tel-eh’-o from 1909 and 5055; to fulfill further (or completely), i.e. execute; by implication, to terminate, undergo:–accomplish, do, finish, (make) (perfect), perform(X -ance).
I believe then, that this means: Behold! A perfect completion!
Amen! Come quickly LORD Jesus!
