'Faithful' in the Bible

For the choir director; upon an eight-stringed lyre. A Psalm of David.Help, Lord, for the godly man ceases to be,For the faithful disappear from among the sons of men.

O love the Lord, all you His godly ones!The Lord preserves the faithfulAnd fully recompenses the proud doer.

And not be like their fathers,A stubborn and rebellious generation,A generation that did not prepare its heartAnd whose spirit was not faithful to God.

For their heart was not steadfast toward Him,Nor were they faithful in His covenant.

“It shall be established forever like the moon,And the witness in the sky is faithful.” Selah.

My eyes shall be upon the faithful of the land, that they may dwell with me;He who walks in a blameless way is the one who will minister to me.

I have chosen the faithful way;I have placed Your ordinances before me.

All Your commandments are faithful;They have persecuted me with a lie; help me!
