[90:5]  ¹ tn Heb “you bring them to an end [with] sleep.” The Hebrew verb זָרַם (zaram) has traditionally been taken to mean “flood” or “overwhelm” (note the Polel form of a root זרם in Ps 77:17, where the verb is used of the clouds pouring down rain). However, the verb form here is Qal, not Polel, and is better understood as a homonym meaning “to make an end [of life].” The term שֵׁנָה (shenah, “sleep”) can be taken as an adverbial accusative; it is a euphemism here for death (see Ps 76:5-6).

[103:15]  ² tn Heb “[as for] mankind, like grass [are] his days.” The Hebrew noun אֱנוֹשׁ (’enosh) is used here generically of human beings. What is said is true of all mankind.
