George Haydock's Catholic Commentary
Psalms 87:15
Prayer. Some copies of the Septuagint read "soul," with the Hebrew, &c. (Calmet) --- Why dost thou neglect to grant my request, which I urge with all the earnestness of my soul? (Haydock) --- This may relate to Jesus in the garden. (Calmet) --- His prayer prevents, or is presented early, (Menochius) and with the truest fervour to the Lord, who moves us to pray. (Haydock)
