Psalms 119:81
CAPH. My soul fainteth for thy salvation,
Either for temporal salvation and deliverance from enemies; which, being promised, was expected by him from the Lord; but not coming so soon as looked for, his spirits began to sink and faint: or for spiritual and eternal salvation, for a view of interest in it, for the joys and comforts of it, and for the full possession of is in heaven; and, particularly, for the promised Messiah, the author of it, often called the Salvation of God, because prepared and appointed by him to be the author of it: of him there was a promise, which gave the Old Testament saints reason to expect him, and for him they waited; his coming they earnestly wished for, but being long deferred, were sometimes out of heart, and ready to faint, which was here David's case;
[but] I hope in thy word;
the word of promise concerning deliverance and salvation, especially by the Messiah, which supported him, and kept him from fainting; that being firm and sure, for ever settled in heaven, and has the oath of God annexed to it, for the confirmation of it; and God is faithful that has promised, and is also able to perform; so that his word lays a solid foundation for faith and hope.
