But his delight [is] in the law of the LORD; and in his law doth he meditate day and night.
Ver. 2. But his delight is in the law of the Lord] i.e. In the whole doctrine of the Holy Scriptures, that invariable rule of truth, as Irenaeus rightly calleth it, Kανων της αληθειας ακλινης. He findeth rest nowhere, nisi in angulo cum libello, in a nook with this book, as Thomas Kempis was wont to say, who also with his own hand wrote out the Bible. King Alphonsus read it over fourteen times, together with such commentaries as those times afforded. Luther said he would not live in paradise without the word, as with it he could live well enough in hell. Magdalen, wife to Dr Paraeus, after she was married, and forty years of age, out of love to the Scriptures, learned to read, and took such delight in it, and especially in the Psalms, that she got them almost all by heart (Par. in Epist. ad Ja. Newer. Pastor. Heidelb.). Beza, being above fourscore years old, could say perfectly by heart any Greek chapter in St Paul's Epistles. Cranmer and Ridley had all the New Testament by heart; the former had learned it in his journey to Rome, the latter in the walks of Pembroke Hall in Cambridge.
And in his law doth he meditate day and night] Hoc primus repetens opus, hoc postremus omittens (Horat.). Having gathered with the bees the sweet of those heavenly flowers, he doth by meditation work his honeycomb within his hive; and at this work he is perdius et pernox, till he feel it to become an ingrafted word, yea, till he hath turned it in succum et sanguinem, and is after a sort transformed into it, 2 Corinthians 3:18. The Hebrew word Hagah here signifieth both to speak with the mouth and with the heart, to read and to meditate; because to read is not to run over a chapter, as a child at school, but to muse upon the matter, and to make some benefit of it. It is said of Pythagoras that he lived in a cave for a whole year together, that, being sequestered from the society of men, he might the better meditate upon the abstruser parts of philosophy; he used also with a thread to tie the hair of his head to a beam over him, that so when he did but nod by reason of sleep he might be awakened thereby. Is not this check to our drowsiness and carelessness of searching the Scriptures, and making them our daily and nightly study? Jerome exhorted some godly women to whom he wrote not to lay the Bible out of their hands until, being overcome with sleep, and not able any longer to hold up their heads, they bowed them down, as it were, to salute the leaves below them with a kiss. (Jerome ad Eust. De custod. Virgin.)
