23 All these things are the book of the covenant of the most high God, even the law which Moses commanded for an heritage unto the congregations of Jacob.

25 He filleth all things with his wisdom, as Phison and as Tigris in the time of the new fruits.
26 He maketh the understanding to abound like Euphrates, and as Jordan in the time of the harvest.

29 For her thoughts are more than the sea, and her counsels profounder than the great deep.
30 I also came out as a brook from a river, and as a conduit into a garden.
31 I said, I will water my best garden, and will water abundantly my garden bed: and, lo, my brook became a river, and my river became a sea.
32 I will yet make doctrine to shine as the morning, and will send forth her light afar off.
