6 And the words of the LORD are flawless, like silver purified in a crucible, like gold refined seven times.
3 Though you probe my heart, though you examine me at night and test me, you will find that I have planned no evil; my mouth has not transgressed.
30 As for God, his way is perfect: The LORD’s word is flawless; he shields all who take refuge in him.
2 Test me, LORD, and try me, examine my heart and my mind;
10 For you, God, tested us; you refined us like silver.
19 till what he foretold came to pass, till the word of the LORD proved him true.
140 Your promises have been thoroughly tested, and your servant loves them.
