On the next day, when Moses went into the tent of the Testimony, look! Aaron’s rod for the house of Le′vi had budded and was bringing forth buds and blossoming flowers and bearing ripe almonds. – Numbers 17:8
While all the other rods remained as they were. Aaron’s rod became a living branch.It wasn’t that Aaron’s rod became fruitful overnight but the development of its natural growth was manifest in all its different stages. In some places there were buds, in others blossoms, in others fruit, at the same time; all this was miraculous. The budding of Aaron’s rod was Jehovah’s sign of approval of Aaron’s appointment as high priest and his descendants. In a similar way Jesus himself proved to be the true High Priest over the House of God by coming forth as “a rod [or shoot] out of the stem of Jesse” (Isaiah 11:1).Also Jesus is portrayed as “a root out of a dry ground” (Isaiah 53:2) fittingly represented by the rod of Aaron that came to life over night from a dead to a living condition. The miraculous shooting forth of Aaron’s dry rod can also be seen as a type of the way the holy spirit operates in the Christian congregation today , and more specifically in the way the holy spirit plays an active role in the gathering of anointed today :‘“Not by a military force, nor by power, but by my spirit,”says Jehovah of armies. (Zechariah 4:6).
“and bearing ripe almonds” the word shaked (almond-tree) is a cognate form of the verb shakad—to keep watch. According to Jewish linguistic scholars this name was given to the almond-tree because it blossoms at a time when most vegetation lies dormant under the winter weather. (See Jeremiah 1:11-12)
In a similar way a “rod of an almond-tree” was shown to the prophet Jeremiah (Jeremiah 1:11) as the evident symbol of the vigilant haste with which the purposes of God were to be developed and matured. It is quite possible that all the tribe heads had official “rods” of the almond-tree to signify denote their watchful readiness in duty, and that these were the rods which they brought to Moses.
