Psalms 38:16

“For I said, [hear me], etc.] This he had expressed in prayer to God; he had committed his cause to him, and entreated him that he would hear and answer him; giving this as a reason, lest [otherwise] they should rejoice over me; at his misfortunes and calamities, at the continuance of his trouble and distress, both of body and mind; when my foot slippeth; as it sometimes did through the corruptions of nature, the temptations of Satan, and the snares of the world; which is more or less the case of all the people of God, who are all subject to slips and falls, though they shall not finally and totally fall away; they magnify [themselves] against me; that is, his enemies exulted and triumphed…”

“For I said - This is the prayer to which he referred in the previous verse. He prayed that he might not be permitted to fall away under the influence of his sins and sufferings; that his faith might remain firm; that he might not be allowed to act so as to justify the accusations of his enemies, or to give them occasion to rejoice over his fall. The entire prayer Psalms 38:16-18 is one that is based on the consciousness of his own weakness, and his liability to sin, if left to himself; on the certainty that if God did not interpose, his sins would get the mastery over him, and he would become in his conduct all that his enemies desired, and be in fact all that they had falsely charged on…”

“When - When I fall into any misery, they triumph in the accomplishment of their desires. Psalms 38:17”

“For I said: Psa 13:3, Psa 13:4, Psa 35:24-26 foot: Psa 94:18; Deu 32:35 magnify: Psa 35:26 Psalms 38:17”
