[1:7] 2 tn Heb “so you can be careful to do.” The use of the infinitive לִשְׁמֹר (lishmor, “to keep”) after the imperatives suggests that strength and bravery will be necessary for obedience. Another option is to take the form לִשְׁמֹר as a vocative lamed (ל) with imperative (see Isa 38:20 for an example of this construction), which could be translated, “Indeed, be careful!”
[1:7] 3 tn Heb “commanded you.”
[1:7] 4 tn Heb “be wise,” but the word can mean “be successful” by metonymy.
