[4:23] 1 tn Heb “more than all guarding.” This idiom means “with all vigilance.” The construction uses the preposition מִן (min) to express “above; beyond,” the word “all” and the noun “prison; guard; act of guarding.” The latter is the use here (BDB 1038 s.v. מִשְׁמָר).
[4:23] 2 sn The word תּוֹצְאוֹת (tots’ot, from יָצָא, yatsa’) means “outgoings; extremities; sources.” It is used here for starting points, like a fountainhead, and so the translation “sources” works well.
