Psalm 62:11 New English Translation

¹¹God has declared one principle;
two principles I have heard:^[a]
God is strong,^[b]

Psalm 62:11 tn Heb “one God spoke, two which I heard.” This is a numerical saying utilizing the “x” followed by “x + 1” pattern to facilitate poetic parallelism. (See W. M. W. Roth, Numerical Sayings in the Old Testament [VTSup], 55-56.) As is typical in such sayings, a list corresponding to the second number (in this case “two”) follows. Another option is to translate, “God has spoken once, twice [he has spoken] that which I have heard.” The terms אַחַת (ʾakhat, “one; once”) and שְׁתַיִם (sh^etayim, “two; twice”) are also juxtaposed in 2 Kgs 6:10 (where they refer to an action that was done more than “once or twice”) and in Job 33:14 (where they refer to God speaking “one way” and then in “another manner”).
Psalm 62:11 tn Heb “that strength [belongs] to God.”
