They were tempted, since the Lord seemed deaf, to try those appalling deities who demanded so much more and might therefore perhaps give more in return. But when a Jew in some happier hour, or a better Jew even in that hour, looked at those worships — when he thought of sacred prostitution, sacred sodomy, and the babies thrown into the fire for Moloch — his own ‘Law’ as he turned back to it must have shone with an extraordinary radiance. Sweeter than honey; or if that metaphor does not suit us who have not such a sweet tooth as all ancient peoples (partly because we have plenty of sugar), let us say like mountain water, like fresh air after a dungeon, like sanity after a nightmare.
First he thinks of the sky; day after the day, the pageantry we see there shows us the splendor of its Creator. Then he thinks of the sun, the bridal joyousness of its rising, the unimaginable speed of its daily voyage from east to west. Finally, of its heat; not of course the mild heats of our climate but the cloudless, blinding, tyrannous rays of hammering the hills, searching every cranny. The key phrase on which the whole poem depends is "there is nothing hid from the heat thereof'. It pierces everywhere with its strong, clean ardor. Then at once, in verse 7 he is talking of something else, which hardly seems to him something else because it is so like the all-piercing, all-detecting sunshine. The Law is 'undefiled', the Law gives light, it is clean and everlasting, it is 'sweet'. No one can improve on this and noting can more fully admit us to the old Jewish feeling about the Law; luminous, severe, disinfectant, exultant, One hardly needs to add that this poet is wholly free from self-righteousness and the last section is concerned with his "secret faults." As he has felt the sun, perhaps in the desert, searching him out in every nook of shade where he attempted to hide from it, so he feels the Law searching out all the hiding-places of his soul.
In so far as this idea of the Law's beauty, sweetness, or preciousness, arose from the contrast of the surrounding Paganisms, we may soon find occasion to cover it. Christians increasingly live on a spiritual island; new and rival ways of life surround it in all directions and their tides come further up the beach every time...
Some give morality a wholly new meaning which we cannot accept, some deny its possibility. Perhaps we shall all learn, sharply enough, to value the clean air and 'sweet reasonableness' of the Christian ethic which...we might have taken for granted.
