15 Those who walk righteously
and speak what is right,
who reject gain from extortion
and keep their hands from accepting bribes,
who stop their ears against plots of murder
and shut their eyes against contemplating evil—
16 they are the ones who will dwell on the heights,
whose refuge will be the mountain fortress.
Their bread will be supplied,
and water will not fail them.
17 Your eyes will see the king in his beauty
and view a land that stretches afar.
The true believer watches against all occasions of sin. The Divine power will keep him safe, and his faith in that power will keep him easy. He shall want nothing needful for him. Every blessing of salvation is freely bestowed on all that ask with humble, believing prayer; and the believer is safe in time and for ever. Those that walk uprightly shall not only have bread given, and their water sure, but they shall, by faith, see the King of kings in his beauty, the beauty of holiness. -Matthew Henry’s Concise Commentary
