Psalm 18:30; Psalm 19:8; Psalm 33:4

30 As for God, his way is perfect: The LORD’s word is flawless; he shields all who take refuge in him.
8 The precepts of the LORD are right, giving joy to the heart. The commands of the LORD are radiant, giving light to the eyes.
4 For the word of the LORD is right and true; he is faithful in all he does.
