Heb 9:4, 9-12, 15, Jn 11:25

In the Old Testament, the Israelites complained to God, and many Israelites were killed by God. When the complaining Israelites saw God's power to make Aaron's rod sprout, they stopped complaining, and God stopped killing the Israelites. (Numbers 17:5,8,10)

Numbers 17:5 And it shall come to pass, that the man's rod, whom I shall choose, shall blossom: and I will make to cease from me the murmurings of the children of Israel, whereby they murmur against you. 8 And it came to pass, that on the morrow Moses went into the tabernacle of witness; and, behold, the rod of Aaron for the house of Levi was budded, and brought forth buds, and bloomed blossoms, and yielded almonds. 10 And the Lord said unto Moses, Bring Aaron's rod again before the testimony, to be kept for a token against the rebels; and thou shalt quite take away their murmurings from me, that they die not.

Aaron's rod that budded in the Old Testament shows the power of God's resurrection. Jesus is the power of God's resurrection. Those who believe in Jesus as the Christ will have eternal life and will be resurrected. (Heb 9:4,9-12,15, John 11:25)

Heb 9:4 Which had the golden censer, and the ark of the covenant overlaid round about with gold, wherein was the golden pot that had manna, and Aaron's rod that budded, and the tables of the covenant; 9 Which was a figure for the time then present, in which were offered both gifts and sacrifices, that could not make him that did the service perfect, as pertaining to the conscience; 10 Which stood only in meats and drinks, and divers washings, and carnal ordinances, imposed on them until the time of reformation. 11 But Christ being come an high priest of good things to come, by a greater and more perfect tabernacle, not made with hands, that is to say, not of this building; 12 Neither by the blood of goats and calves, but by his own blood he entered in once into the holy place, having obtained eternal redemption for us. 15 And for this cause he is the mediator of the new testament, that by means of death, for the redemption of the transgressions that were under the first testament, they which are called might receive the promise of eternal inheritance.

John 11:25 Jesus said unto her, I am the resurrection, and the life: he that believeth in me, though he were dead, yet shall he live:
