Psalms 119:2

Blessed are they that keep his testimonies -His commandments or laws, considered as what he bears witness to concerning that which is just, wise, good. Every law of a parent is to his children a testimony on his part of what is wise and right and good; and so every law of God is his solemn testimony as to what is right and good for man. SeePsalms 19:7, note;Psalms 25:10, note. And that seek him with the whole heart -With a sincere desire to know his will and to do it; without hypocrisy or guile; with no selfish or sinister aims. As God knows the heart, all other modes of “seeking” him must be in vain.
