Still more on the offerings for Shavuot - the lambs and the loaves. Namely, showing the lambs in the 4 directions, plus up and down, to demonstrate God's province of the heavens and the earth. Or alternatively, to acknowledge and pray that nothing bad befall the people, from any which direction. With parallels, of course, to lulav and the waving thereof. Plus, the fulfillment of mitzvot as a means of thwarting the Satan - unless taking that gleeful approach is taunting him or inviting him to challenge the person keeping the mitzvot. Also, 3 animal offerings that each need 3 mitzvot in accompaniment, with all the concomitant details - including waving while the animal is either alive or no longer so. Note that no sacrifice required all three of those accompanying mitzvot - usually, 2 out of 3. Plus, the question of whether the laying on of hands (semikhah) would be required.
