Therefore we are commanded to search the Scriptures as for silver [John 5:39], and to seek in them as for treasures, to read in them continually, to meditate on them day and night [Ps. 1:2], to use them as bracelets upon our arms, and frontlets between our eyes [Deut. 6:8], to teach them to our posterity, and to talk of them when we are in our houses, and when we walk by the way, when we lie down, and when we are up.  And great reason there is of this commandment, seeing that (as an ancient writer says) Quicquid in eis docetur veritas est: quicquid praecipitur bonitas est: quicquid promittitur faelicitas est – that is, “Whatsoever is taught in them, is truth itself; whatsoever is commanded, is goodness itself; whatsoever is promised, is happiness itself.”  They being of such perfection, that nothing may be added unto them, or any thing taken from them [Deut. 4:2]; of such infallible certainty, that heaven and earth shall sooner pass away, than one tittle fall to the ground [Matt. 5:18]; so pleasant and delightful, that they exceed the honey and the honeycomb; and so profitable, that no treasures may be compared unto them [Ps. 19:10], seeing they are able to make us wiser than our enemies, than the aged, than our teachers [Ps. 119:98, etc.]; to make us wise unto salvation [2 Tim. 3:15]; to give us an inheritance among them that are sanctified [Acts 20:32]; nay, able to save our souls [James 1:21].
