“And he put a new canticle into my mouth, a song to our God. Many shall see, and shall fear: and they shall hope in the Lord.”

“Blessed-- (Psa 1:1; Psa 2:12). respecteth--literally, "turns towards," as an object of confidence. turn aside--from true God and His law to falsehood in worship and conduct.”
