[74:17] 1 tn This would appear to refer to geographical boundaries, such as mountains, rivers, and seacoasts. However, since the day-night cycle has just been mentioned (v. 16) and the next line speaks of the seasons, it is possible that “boundaries” here refers to the divisions of the seasons. See C. A. Briggs and E. G. Briggs, Psalms (ICC), 2:156.
[74:17] 2 tn Heb “summer and winter, you, you formed them.”
[89:47] 3 tn Heb “remember me, what is [my] lifespan.” The Hebrew term חֶלֶד (kheled) is also used of one’s lifespan in Ps 39:5. Because the Hebrew text is so awkward here, some prefer to emend it to read מֶה חָדֵל אָנִי (meh khadel ’aniy, “[remember] how transient [that is, “short-lived”] I am”; see Ps 39:4).
[89:47] 4 tn Heb “For what emptiness do you create all the sons of mankind?” In this context the term שָׁוְא (shavah) refers to mankind’s mortal nature and the brevity of life (see vv. 45, 48).
