Numbers 32:23

32:23 “But if you do not do this, then look, you will have sinned ³  against the Lord. And know that your sin will find you out.

[15:32]  ¹ tn The preterite of the verb “to be” is here subordinated to the next, parallel verb form, to form a temporal clause.

[15:32]  ² sn For this brief passage, see A. Phillips, “The Case of the Woodgatherer Reconsidered,” VT 19 (1969): 125-28; J. Weingreen, “The Case of the Woodgatherer (Numbers XV 32-36),” VT 16 (1966): 361-64; and B. J. Bamberger, “Revelations of Torah after Sinai,” HUCA 16 (1941): 97-113. Weingreen argues that there is something of the Rabbinic method of setting a fence around the Law here; in other words, if this sin were not punished, the Law would have been violated in greater ways. Gathering of wood, although seemingly harmless, is done with intent to kindle fire, and so reveals a culpable intent.

[32:23]  ³ tn The nuance of the perfect tense here has to be the future perfect.
