Exodus 4:9

4:9 And if they do not believe even these two signs or listen to you, then take some water from the Nile and pour it out on the dry ground. The water you take out of the Nile will become blood on the dry ground.”

Exodus 12:22

12:22 Take a branch of hyssop, dip it in the blood that is in the basin, and apply to the top of the doorframe and the two side posts some of the blood that is in the basin. Not one of you is to go out the door of his house until morning.

Exodus 29:20

29:20 and you are to kill the ram and take some of its blood and put it on the tip of the right ear of Aaron, on the tip of the right ear of his sons, on the thumb of their right hand, and on the big toe of their right foot, and then splash the blood all around on the altar.

Exodus 30:10

30:10 Aaron is to make atonement on its horns once in the year with some of the blood of the sin offering for atonement; once in the year 10  he is to make atonement on it throughout your generations. It is most holy to the Lord.” 11 


tn Heb “and it will be if.”

tn Heb “listen to your voice.”

tn The verb form is the perfect tense with the vav (ו) consecutive; it functions then as the equivalent of the imperfect tense – here as an imperfect of instruction.

sn This is a powerful sign, for the Nile was always known as the source of life in Egypt, but now it will become the evidence of death. So the three signs were alike, each consisting of life and death. They would clearly anticipate the struggle with Egypt through the plagues. The point is clear that in the face of the possibility that people might not believe, the servants of God must offer clear proof of the power of God as they deliver the message of God. The rest is up to God.

sn The hyssop is a small bush that grows throughout the Sinai, probably the aromatic herb Origanum Maru L., or Origanum Aegyptiacum. The plant also grew out of the walls in Jerusalem (1 Kgs 4:33). See L. Baldensperger and G. M. Crowfoot, “Hyssop,” PEQ 63 (1931): 89-98. A piece of hyssop was also useful to the priests because it worked well for sprinkling.

tn The Greek and the Vulgate translate סַף (saf, “basin”) as “threshold.” W. C. Kaiser reports how early traditions grew up about the killing of the lamb on the threshold (“Exodus,” EBC 2:376).

tn Heb “and you, you shall not go out, a man from the door of his house.” This construction puts stress on prohibiting absolutely everyone from going out.

sn By this ritual the priests were set apart completely to the service of God. The ear represented the organ of hearing (as in “ears you have dug” in Ps 40 or “awakens my ear” in Isa 50), and this had to be set apart to God so that they could hear the Word of God. The thumb and the hand represented the instrument to be used for all ministry, and so everything that they “put their hand to” had to be dedicated to God and appropriate for his service. The toe set the foot apart to God, meaning that the walk of the priest had to be consecrated – where he went, how he conducted himself, what life he lived, all belonged to God now.

tn The word “atonements” (plural in Hebrew) is a genitive showing the result or product of the sacrifice made.

10 sn This ruling presupposes that the instruction for the Day of Atonement has been given, or at the very least, is to be given shortly. That is the one day of the year that all sin and all ritual impurity would be removed.

11 sn The phrase “most holy to the Lord” means that the altar cannot be used for any other purpose than what is stated here.
