"The psalmist declares, “Thy word have I hid in mine heart, that I might not sin against Thee.” [ Psalm 119:11 .] And Paul wrote to Timothy, “All Scripture is given by inspiration of God, and is profitable for doctrine, for reproof, for correction, for instruction in righteousness: that the man of God may be perfect, thoroughly furnished unto all good works.” [ 2 Timothy 3:16, 17 .] GW 250.1"
"Thy word have I hid in mine heart, that I might not sin against thee."
Ellen White directly references Psalms 119:11 in this passage.
