[23:39]  ¹ tn Heb “Surely on the fifteenth day.” The Hebrew adverbial particle אַךְ (’akh) is left untranslated by most recent English versions; however, cf. NASB “On exactly the fifteenth day.”

[8:33]  ² tn Heb “because seven days he shall fill your hands”; KJV “for seven days shall he consecrate you”; CEV “ends seven days from now.”
