1 sn The verse is describing the way God can preserve someone from dying by sending a messenger (translated here as “angel”), who could be human or angelic. This messenger will interpret/mediate God’s will. By “one … out of a thousand” Elihu could have meant either that one of the thousands of messengers at God’s disposal might be sent or that the messenger would be unique (see Eccl 7:28; and cp. Job 9:3).
2 tn This is a smoother reading. The MT has “to tell to a man his uprightness,” to reveal what is right for him. The LXX translated this word “duty”; the choice is adopted by some commentaries. However, that is too far from the text, which indicates that the angel/messenger is to call the person to uprightness.
