1 tn Heb “Be careful at the risk of your lives.” The expression with the preposition בְּ (bet) is unique. Elsewhere the verb “be careful” is used with the preposition לְ (lamed) in the sense of the reflexive. Hence the word “soul” cannot be simply reflexive here. BDB 1037 s.v. שָׁמַר Niph.1 understands this as a case where the preposition בְּ introduces the cost or price (cf. BDB 90 s.v. בּ III.3.a).
2 sn Comparison with Neh 13:15-18 suggests that these loads were merchandise or agricultural produce which were being brought in for sale. The loads that were carried out of the houses in the next verse were probably goods for barter.
3 tn Heb “carry loads on the Sabbath and bring [them] in through.” The two verbs “carry” and “bring in” are an example of hendiadys (see the note on “Be careful…by carrying”). This is supported by the next line where only “carry out” of the houses is mentioned.
