1Sa 13:9, So Saul said, “Bring a burnt offering and peace offerings here to me.” AND HE OFFERED THE BURNT OFFERING.
Saul was a king but not a priest! Also reminds me of king Uzziah who did right according to the LORD Yet, was plagued with Leprosy for burning incense to the LORD! 2Chr 26:16-20.
2Ch 26:16, But when he was strong his heart was lifted up, TO HIS DESTRUCTION, for he transgressed against the LORD his God by entering the temple of the LORD TO BURN INCENSE ON THE ALTAR OF INCENSE.
1Sa 13:11, And Samuel said, “WHAT HAVE YOU DONE?” Saul said, “When I saw that the people were scattered from me, AND THAT YOU DID NOT COME WITHIN THE DAYS APPOINTED, and that the PHILISTINES GATHERED TOGETHER AT MICHMASH,
Saul, like a child, blames Samuel for not showing up on time! He felt compelled to do the work of a priest (ver 13)
THERE IS ONLY ONE KING AND PRIEST AND THAT IS THE LORD JESUS. HE IS THE KING OF kings AND LORD OF lords! HE IS ALSO THE GREAT HIGH PRIEST WHO OFFERED HIMSELF RATHER THAN THE BLOOD OF BULLS AND GOATS TO COVER OUR SINS!
Heb 4:14-15, Seeing then that we have a great High Priest who has passed through the heavens, Jesus the Son of God, let us hold fast our confession. For we do not have a High Priest who cannot sympathize with our weaknesses, but was in all points tempted as we are, YET WITHOUT SIN.
