David's other psalms also reveal the rich relationship between David and God. David spoke to God with such endearing terms as "my shepherd" (Ps. 23:1), "my strong deliverer" (Ps. 140:7), and "my loving God" (Ps. 59:17). At times he wore himself out crying to God (Ps. 6), on occasion he voiced his doubts (Ps. 13), and other times could barely contain his praise (Ps. 145).
