hadliku “
V’HADliku means the imperative plural command “And (You) light!
V’HIDliku (which unless I am mistaken, is the way we read this word here) means “And they lit.” And even these meanings would be changed were we to assume that tjhe VOV at the beginning of the word is the VOV hamihapeches, that changes the loshon of avar (past tense) to asid (future tense). It could be a hint to what we now do today.
