72 Heb “From days to days,” a Hebrew idiom for “annually.”
73 Heb “go to commemorate.” The rare Hebrew verb תָּנָה (tanah, “to tell; to repeat; to recount”) occurs only here and in 5:11.
74 The Hebrew text adds, “in the year.” This is redundant (note “every year” at the beginning of the verse) and has not been included in the translation for stylistic reasons.
