Tehillim 18:30-32 Orthodox Jewish Bible (OJB)
30 (31) As for El, His derech is tamim (perfect); the word of Hashem is tzerufah (tested and proved flawless, inerrant); He is a mogen to all those that take refuge in Him.
31 (32) For who is Elohim besides Hashem? Or who is Tzur but Eloheinu?
32 (33) It is El that armeth me with chayil, and maketh my derech tamim (perfect).
