But as for me - In respect to my conduct and my feelings in these circumstances, and under this treatment.
My prayer is unto thee - I indulge in no reproaches of others, and no recriminations. I do not permit myself to indulge in any revengeful feelings. I give myself to prayer. I look to God alone. I keep up my devotions, I maintain my habits of religion, notwithstanding their reproaches, and revilings. I do not allow these things to alter my course of life. Compare the notes at Daniel 6:10.
In an acceptable time - A time that is well-pleasing to thee; a time when thou wilt hear me. See Isa. 49:83; Isaiah 61:2; 2 Corinthians 6:2. This implies
(a) that he had come to God when he was “disposed” to hear; and
(b) that he had heard him, and had answered his requests.
While others mocked, he continued to pray, and the Lord heard him. No time for prayer can be more “acceptable” to God than when others are reproaching us because we are his friends.
In the multitude of thy mercy hear me - In the abundance of thy mercy; or, in thy abounding compassion. This was the substance of his prayer.
In the truth of thy salvation - In the exercise of that faithfulness on which salvation depends; or which is manifested in the salvation of people. He prayed that God would show himself faithful to the promises which he had made to those who were seeking salvation.
