Then called I upon the name of the Lord - Upon the Lord. I had no other refuge. I felt that I must perish unless he should interpose, and I pleaded with him for deliverance and life. Compare the notes at Psalm 18:6.
O Lord, I beseech thee, deliver my soul - My life. Save me from death. This was not a cry for salvation, but for life. It is an example for us, however, to call on God when we feel that the soul is in danger of perishing, for then, as in the case of the psalmist, we have no other refuge but God.

Then called I upon the name of the Lord,.... Upon the Lord himself in prayer for speedy deliverance; or "in the name of the Lord" (h), in the name of the Messiah, the only Mediator between God and man; "saying", as follows, and which word may be supplied,
O Lord, I beseech thee, deliver my soul; from these sorrows and pains, from these afflictions and distresses, from death and the grave, and from wrath, and a sense of it, and fears about it.
(h) "in nomine Domini", Montanus, Musculus, Vatablus.
