Keluaran 12:22

12:22 Take a branch of hyssop, ¹  dip it in the blood that is in the basin, ²  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 ³  the door of his house until morning.

Bilangan 19:18

19:18 Then a ceremonially clean person must take hyssop, dip it in the water, and sprinkle it on the tent, on all its furnishings, and on the people who were there, or on the one who touched a bone, or one killed, or one who died, or a grave.

Mazmur 51:7

51:7 Sprinkle me ⁴  with water ⁵  and I will be pure; ⁶ 

wash me ⁷  and I will be whiter than snow. ⁸ 

[12:22]  ¹ 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.

[12:22]  ² 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).

[12:22]  ³ 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.

[51:7]  ⁴ tn The imperfect verbal form is used here to express the psalmist’s wish or request.

[51:7]  ⁵ tn Heb “cleanse me with hyssop.” “Hyssop” was a small plant (see 1 Kgs 4:33) used to apply water (or blood) in purification rites (see Exod 12:22; Lev 14:4-6, 49-52; Num 19:6-18. The psalmist uses the language and imagery of such rites to describe spiritual cleansing through forgiveness.

[51:7]  ⁶ tn After the preceding imperfect, the imperfect with vav (ו) conjunctive indicates result.

[51:7]  ⁷ tn The imperfect verbal form is used here to express the psalmist’s wish or request.

[51:7]  ⁸ sn I will be whiter than snow. Whiteness here symbolizes the moral purity resulting from forgiveness (see Isa 1:18).
