My heart is steadfast, God. I will sing and I will make music with my soul.

He will not be afraid of evil news. His heart is steadfast, trusting in Yahweh.

Oh that my ways were steadfast to obey your statutes!

You will keep whoever's mind is steadfast in perfect peace, because he trusts in you.

I make a decree, that in all the dominion of my kingdom men tremble and fear before the God of Daniel; for he is the living God, and steadfast forever, His kingdom that which shall not be destroyed; and his dominion shall be even to the end.
