Deuteronomy 6:24

And the Lord commanded us to do all these statutes
Some of which were designed on purpose to commemorate the wonderful deliverance out of Egypt, as particularly the passover; and all of them they were obliged in gratitude to obey, in consideration of such great favours bestowed upon them:

to fear the Lord our God, for our good always:
as it is always for the good of men, temporal, spiritual, and eternal, to fear the Lord; for there is no want to them that fear him, nor will the Lord withhold good things from them; see ( Psalms 34:9 Psalms 34:10 ) ,

that he might preserve us alive, as it is at this day;
in bodily health and strength, and in the enjoyment of the good land, and all the blessings and benefits of it.
