Mazmur 78:51

78:51 He struck down all the firstborn in Egypt,

the firstfruits of their reproductive power ¹  in the tents of Ham.

Mazmur 105:36

105:36 He struck down all the firstborn in their land,

the firstfruits of their reproductive power. ² 

[78:51]  ¹ tn Heb “the beginning of strength.” If retained, the plural form אוֹנִים (’onim, “strength”) probably indicates degree (“great strength”), but many ancient witnesses read “their strength,” which presupposes an emendation to אֹנָם (’onam; singular form of the noun with third masculine plural pronominal suffix).

[105:36]  ² tn Heb “the beginning of all their strength,” that is, reproductive power (see Ps 78:51).

[105:36]  sn Verses 28-36 recall the plagues in a different order than the one presented in Exodus: v. 28 (plague 9), v. 29 (plague 1), v. 30 (plague 2), v. 31a (plague 4), v. 31b (plague 3), vv. 32-33 (plague 7), vv. 34-35 (plague 8), v. 36 (plague 10). No reference is made in Ps 105 to plagues 5 and 6.
