Numbers 1:47 tn The vav (ו) on this word indicates a disjunction with the previous sequence of reports. It may be taken as a contrastive clause, translated “but” or “however.”

Numbers 1:47 tc The form in the text is הָתְפָּקְדוּ (hotpaq^edu); if this is correct, then it is an isolated instance of the reflexive of the Qal of פָּקַד (paqad). Some, however, explain the form as the Hitpael without the doubling of the middle letter and with a compensatory lengthening of the vowel before it (G. B. Gray, Numbers [ICC], 10).
Numbers 1:48 tn Heb “had spoken to Moses, saying.” The infinitive construct of אָמַר (ʾamar), sometimes rendered “saying” in older English translations, does not need to be translated, but can be taken simply as the indicator of direct discourse. Most recent English translations, including the present one, leave the form untranslated for stylistic reasons to avoid redundancy.
