David knew exactly what the enemy was saying and doing, and we need to know the strategy of Satan when he attacks us (2 Cor. 2:11). As a lion, he comes to devour (1 Peter 5:8), and as a serpent, he comes to deceive (2 Cor. 11:1–4), and one of his chief weapons is accusation (Rev. 12:10; Zech. 3). David compared his enemies’ tongues to swords (55:21; 57:4; 59:7) and their words to poisoned arrows (57:4; Prov. 25:18; 26:18–19; Jer. 9:8). But they also set traps for him, confident that nobody knew what they were doing, not even the Lord (10:11, 13; 12:4; 59:7). (For some of Saul’s traps and how the Lord frustrated them, see 1 Sam. 18—19.) David knew that the human heart is “deep” (“cunning,” niv; see Jer. 17:9) and that there are always new dangers to avoid, so he constantly sought the Lord’s wisdom as he made decisions. James 1: is a great promise to claim!
