Exodus 29:16

וזרקת AND THOU SHALT SPRINKLE IT with a vessel: he held the basin and cast blood from it towards the horn in such a manner that it (the blood) showed on both sides of it. No offering except the sin-offering alone required that its blood should be smeared with the finger, but other sacrifices required neither “horn” nor “finger” (did not require that the blood should be placed on the horn of the altar by the fingers), for the sprinkling of their blood had to be upon the lower half of the altar, and he (the priest) therefore did not mount the ascent leading to the top of the altar but he stood on the ground and sprinkled the blood (Zevachim 53b). סביב ROUND ABOUT — This is how it is explained in the Treatise on Slaughtering the Sacrifices (Zevachim 53b): that סביב, “round about” signifies nothing more than that there were to be two sprinklings so made that they should constitute four — one on this corner and one at that which was diagonally opposite it, and so that each sprinkling showed on both sides of the corner, on this and on that side; it followed therefore that the blood was placed on the four sides round about, and for this reason it is here termed סביב.

And thou shalt slay the ram, and thou shalt take its blood, and sprinkle it round about upon the altar.
