Just for (Hebrew) fun

I'm working on a first-year Hebrew grammar right now and ran across this little gem in the chapter on geminates:

note the second person masculine plural form תִּסַּבּוּ the dot in the ת is a dagesh lene, the dot in the ס is the assimilated nun, the dot in the ב is the doubling of the geminate root, and the dot in the ו is the sign of the shureq.

Fun stuff!
