Psalms 40:3
“And he hath put a new song in my mouth, even praise unto our God: many shall see it, and fear, and shall trust in the Lord.”
I waited patiently for the Lord; and he inclined unto me, and heard my cry.
He brought me up also out of an horrible pit, out of the miry clay, and set my feet upon a rock, and established my goings.
And he hath put a new song in my mouth, even praise unto our God: many shall see it, and fear, and shall trust in the Lord.
Blessed is that man that maketh the Lord his trust, and respecteth not the proud, nor such as turn aside to lies.
Many, O Lord my God, are thy wonderful works which thou hast done, and thy thoughts which are to us-ward: they cannot be reckoned up in order unto thee: if I would declare and speak of them, they are more than can be numbered.
