In 1512 B.C.E., when the tabernacle was set up at the foot of Mount Sinai, Moses presided over a ceremony to install Aaron and his sons as priests. (Ex. 40:17; Lev. 9:1-5) How did Jehovah show his approval of the newly installed priesthood? As Aaron and Moses blessed the people, Jehovah caused fire to consume the remainder of the sacrifice on the altar. (Lev. 9:23, 24) What was accomplished by the awesome display at the installation of the high priest? Jehovah thereby showed his full support of the Aaronic priesthood. When the Israelites saw this clear evidence of Jehovah’s backing of the priests, they had good reason to give them full support. Is that relevant to us? Yes! The priesthood in Israel was just a shadow of a much greater priesthood​—the 144,000, who will serve alongside Christ in heaven. (Heb. 4:14; 8:3-5; 10:1) Without a doubt, Jehovah is guiding and generously blessing his organization today. w19.11 23 ¶13; 24 ¶14, 16
