Midrasch zu Mischlej 15:8

"Upon the Torah," whence do we know (this)? Because it is written, "If my covenant of day and night stand not" (Jer. 33:25); and (another text) says, "This book of the Torah shall not depart out of thy mouth, but thou shalt meditate therein day and night" (Josh. 1:8). Whence do we know (that the world rests) upon the service of loving-kindness? Because it is said, "For I desired love, || and not sacrifice" (Hos. 6:6). Whence do we know (that the world rests) upon Divine Worship? Because it is written, "And the prayer of the upright is his delight" (Prov. 15:8).
