In YHWH I take shelter. For behold the wicked have prepared a bow, they have made ready their arrows on the strings, to shoot in the darkness at the upright heart. For the foundations are being overthrown. May he rain 6 on the wicked, traps, fire and brimstone, And a scorching wind will be what they deserve. Confidence in the power and goodness of God are absolutely essential to the life of a godly man or woman.
Confidence is the by-product of the faith, much as fire is the result of an initial spark.
In this psalm, only one person is in the foreground. Although there are a group of people who are represented as the antagonists to faith in God, there is only one man who is expressing trust in God. The focus of the psalm is on the trust of this one individual, presumably David. That David is the author is taken from the Hebrew superscription at the beginning of the psalm, lamnatseach ldawid . Extrabiblically, the Samaria Ostraca and Lachish Letters, which are potsherds and dockets from the days of the divided monarchy, also verify this usage.
