Psalms 119:48

My hands also will I lift up unto thy commandments ... - As an expression of delight or rejoicing, as people lift up their hands with their voice when they give expression to joy. It denotes a high statue of joy, such as leads to an outward expression; not merely that which exists in calm contemplation, but where the heart is full, and when it finds outward expression.

And I will meditate in thy statutes - See the notes at Psalms 1:2. I will indicate my joy - my happiness - in thy commandments in every way possible; by outward expressions, and by deep and calm contemplation when I am alone; in my daily employments, in solitude, in the night-watches. This is indicative always of true religion.
