Psalms 145:11

They shall speak of the glory of thy kingdom - Of thy reign; of the great principles of thy government and laws. They see in that reign evidence that thou art worthy of universal praise. Seeing this, it becomes to them a subject on which they talk or converse (compare Malachi 3:16) - a subject of interest to their hearts, and "out of the abundance of the heart the mouth speaks." People talk about that which interests them; those things in which they have pleasure; those which they desire to understand; those in which they see difficulties that they would wish to have solved. It is one of the characteristics of the "saints" - of the people of God - that they do talk about God and his kingdom; that the subject is to them a pleasant theme of meditation and conversation; that they have the kind of pleasure in talking about God which other people have in conversing about their farms or their merchandise, their children and friends, the news of the day, politics, literature, or science.

And talk of thy power - As put forth in the works of creation; as manifested in the dispensations of thy providence; as evinced in the conversion of sinners; as displayed in carrying thy truth around the world; as exhibited in sustaining fine sufferer, and in giving peace and support to the dying.
