[18:11] 1 tc Heb “he made darkness his hiding place around him, his covering.” 2 Sam 22:12 reads, “he made darkness around him coverings,” omitting “his hiding place” and pluralizing “covering.” Ps 18:11 may include a conflation of synonyms (“his hiding place” and “his covering”) or 2 Sam 22:12 may be the result of haplography/homoioarcton. Note that three successive words in Ps 18:11 begin with the Hebrew letter samek: סִתְרוֹ סְבִיבוֹתָיו סֻכָּתוֹ (sitro sÿvivotayv sukkato).
[18:11] 2 tc Heb “darkness of water, clouds of clouds.” The noun “darkness” (חֶשְׁכַת, kheshkhat) is probably a corruption of an original reading חשׁרת, a form that is preserved in 2 Sam 22:12. The latter is a construct form of חַשְׁרָה (khashrah, “sieve”) which occurs only here in the OT. A cognate Ugaritic noun means “sieve,” and a related verb חָשַׁר (khashar, “to sift”) is attested in postbiblical Hebrew and Aramaic. The phrase חַשְׁרַת מַיִם (khashrat mayim) means literally “a sieve of water.” It pictures the rain clouds as a sieve through which the rain falls to the ground (see F. M. Cross and D. N. Freedman, Studies in Ancient Yahwistic Poetry [SBLDS], 146, n. 33).
[18:12] 3 tc Heb “from the brightness in front of him his clouds came, hail and coals of fire.” 2 Sam 22:13 reads, “from the brightness in front of him burned coals of fire.” The Lucianic family of texts within the Greek tradition of 2 Sam 22:13 seems to assume the underlying Hebrew text: מנגה נגדו עברו ברד וגחלי אשׁ, “from the brightness in front of him came hail and coals of fire” (the basis for the present translation). The textual situation is perplexing and the identity of the original text uncertain. The verbs עָבָרוּ (’avaru; Ps 18:12) and בָּעֲרוּ (ba’aru; 2 Sam 22:13) appear to be variants involving a transposition of the first two letters. The noun עָבָיו (’avayv, “his clouds,” Ps 18:12) may be virtually dittographic (note the following עָבְרוּ, ’avru), or it could have accidentally dropped out from the text of 2 Sam 22:13 by virtual haplography (note the preceding בָּעֲרוּ, which might have originally read עָבְרוּ). The noun בָּרָד (barad, “hail,” Ps 18:12) may be virtually dittographic (note the preceding עָבְרוּ), or it could have dropped out from 2 Sam 22:13 by virtual haplography (note the preceding בָּעֲרוּ, which might have originally read עָבְרוּ).
