1 Kings 15:5

Save only — This and the like phrases are not to be understood as exclusive of every sinful action, hut only of an habitual and continued apostasy from God, as the very phrase of turning aside from God, or from his commands, doth constantly imply. And thus it is most true. For David's other sins were either sudden and transient acts, soon repented of and blotted out, as in the cases of Nabal and Achish; or, mistakes of his judgment, which was not fully convinced of the sinfulness of such actions: whereas that which concerned Uriah's wife was a designed and studied sin, long continued in, defended with a succession of other sins, presumptuous, and scandalous to his government, and to the true religion.
