Take for yourself spices

קַח לְךָ סַמִּים 

34.’ And Hashem said to Moses ‘Take for yourself spices, stacte, onycha, and galburnum, (other-Rashi) spices and pure frankincense, in equal quantities they shall be- וַיֹּאמֶר יְהוָה אֶל מֹשֶׁה קַח לְךָ סַמִּים נָטָף וּשְׁחֵלֶת וְחֶלְבְּנָה סַמִּים וּלְבֹנָה זַכָּה בַּד בְּבַד יִהְיֶה (2270+16 words=2286=18).

The gematria of the words “take for yourself spices”- קַח לְךָ סַמִּים is308= 11.

This corresponds to the 11 spices- סַמִּים  blended in the "Ketoret".

The number 308 also is the gematria of the name “Korach”- קֹרַח!!

Take for yourself spices

קַח לְךָ סַמִּים

308

Korach

קֹרַח

308

This teaches us that Hashem instructed Moses to also make forhimself Ketoret in addition to the Ketoret made by the master spice blender Korach! The incense that Moses made for himself would defeat the incense of Korach in the duel of the fire pans.
