Numbers 16:12 New English Translation

¹²Then Moses summoned^[a] Dathan and Abiram, the sons of Eliab, but they said, “We will not come up.^[b]

Numbers 16:12 tn Heb “Moses sent to summon.” The verb קָרָא (qaraʾ) followed by the ל (lamed) preposition does not mean “call to” but “summon.” This is a command performance; for them to appear would be to submit to Moses’ authority. This they will not do.
Numbers 16:12 tn The imperfect tense of נַעֲלֶה (naʿaleh) expresses their unwillingness to report: “we are not willing,” or “we will not.” The verb means “to go up.” It is used in the sense of appearing before an authority or a superior (see, e.g., Gen 46:31; Deut 25:7; Judg 4:5).
