¹ tn After the preceding imperfect verbal form, the subordinated imperative indicates purpose/result. S. R. Driver comments, “…the imper. is used instead of the more normal voluntative, for the purpose of expressing with somewhat greater force the intention of the previous verb” (S. R. Driver, Notes on the Hebrew Text and the Topography of the Books of Samuel, 350).

² tn Heb “[As for] the God, his way is blameless.” The term הָאֵל (ha’el, “the God”) stands as a nominative (or genitive) absolute in apposition to the resumptive pronominal suffix on “way.” The prefixed article emphasizes his distinctiveness as the one true God (see BDB 42 s.v. II אֵל 6; Deut 33:26). God’s “way” in this context refers to his protective and salvific acts in fulfillment of his promise (see also Deut 32:4; Pss 67:2; 77:13 [note vv. 11-12, 14]; 103:7; 138:5; 145:17).

³ tn Heb “the word of the Lord is purified.” The Lord’s “word” probably refers here to his oracle(s) of victory delivered to the psalmist before the battle(s) described in the following context. See also Pss 12:5-7 and 138:2-3. David frequently received such oracles before going into battle (see 1 Sam 23:2, 4-5, 10-12; 30:8; 2 Sam 5:19). The Lord’s word of promise is absolutely reliable; it is compared to metal that has been refined in fire and cleansed of impurities. See Ps 12:6. In the ancient Near East kings would typically seek and receive oracles from their god(s) prior to battle. For examples, see R. B. Chisholm, “An Exegetical and Theological Study of Psalm 18/2 Samuel 22” (Th.D. diss., Dallas Theological Seminary, 1983), 241-42.

⁴ sn The parallel text in 1 Chr 21:1 says, “An adversary opposed Israel, inciting David to count how many warriors Israel had.” The Samuel version gives an underlying theological perspective, while the Chronicler simply describes what happened from a human perspective. The adversary in 1 Chr 21:1 is likely a human enemy, probably a nearby nation whose hostility against Israel pressured David into numbering the people so he could assess his military strength. See the note at 1 Chr 21:1.
