For thou hast delivered my soul from death - My life. Thou hast saved me from death. This is such language as would be used by one who had been dangerously ill, and who had been restored again to health.
Mine eyes from tears - Tears which he had shed in his sickness, and in the apprehension of dying. It may refer to tears shed on other occasions, but it is most natural to refer it to this. Compare the notes at Psalms 6:6.
And my feet from falling - From stumbling. That is, he had not, as it were, fallen by the way, and been rendered unable to pursue the journey of life. All this seems to refer to one occasion - to a time of dangerous illness.
