Spits on: this gesture is usually a sign of intense dislike or rejection (see Num 12.14; Deut 25.9; Matt 26.67; 27.30). In the first two passages mentioned, it involves “spitting in the face of someone,” but here the action may be accidental or to show contempt. In either case, the person on whom the infected man spits is required to wash his clothing and his entire body.

He shall wash …: the pronoun refers to the man who has been spat on and not the man with the discharge. This should be made clear in the receptor language.
