Today I was reading Numbers 15:4 in Hebrew, and I noticed that the verse opens with three consecutive words, all of which share the same root in Hebrew: קרב. The verse opens like this: וְהִקְרִ֛יב הַמַּקְרִ֥יב קָרְבָּנ֖וֹ. The RSVCE translates it "then he who brings his offering shall offer". In Hebrew, however, the three repeated roots sound more like what in English would sound "The offerer shall offer his offering".
The root is repeated three times in a row, the first two times from the verb lemma, and the third time from a completely different lemma, a noun ("offering").
So, I found this curious and thought I would investigate whether or not there are other verses in the Hebrew Bible which have this root in three consecutive words. This is the search I found that seemed to work best:

So, 11 verses have this root at least three times. Numbers 15:4 is included in the results. Scrolling through the results, there seems to only be one other verse where the root appears three consecutive times, Lev 3:7:

This was confirmed by this subsequent search like this:

If I rerun the search changing "BEFORE 2 WORDS" to "BEFORE 1 WORDS", then only Num 15:4 results, as the search engine considers the את connector to be a word.
Interestingly, the three words used in both Num 15:4 and Lev 3:7 are the same - same verb form, same participle form, same noun form, although the translation of the phrase is quite different.
I thought it might be interesting to do a search in general for any root that appears three consecutive times, but I'm not sure how, or if it is possible. If anyone has any idea please share.
Either way, hope this gets you thinking of how to use this new "root" functionality to study God's Word. It opens up some very interesting new possibilities.
