Law 15: Yahweh's Book of Laws
Deu 6:9 And thou shalt write them upon the posts of thy house, and on thy gates
Matthew Henry Commentaries
It is probable that at that time there were few written copies of the whole law, only at the feasts of tabernacles the people had it read to them; and therefore Yahweh appointed them, at least for the present, to write some select sentences of the law, that were most weighty and comprehensive, upon their walls, or in scrolls of parchment to be worn about their wrists; and some think that hence the phylacteries so much used among the Jews took rise.
Yahshua sblames the Pharisees, not for wearing them, but for affecting to have them broader than other people's, Mat_23:5.
But when Bibles came to be common among them there was less occasion for this expedient. It was prudently and piously provided by the first reformers of the English church that then, when Bibles were scarce, some select portions of scripture should be written on the walls and pillars of the churches, which the people might make familiar to them, in conformity to this direction, which seems to have been binding in the letter of it to the Hebrews as it is to us in the intent of it, which is that we should endeavour by all means possible to make the word of Yahwehfamiliar to us, that we may have it ready to us upon all occasions, for our restraint from sin and our direction and excitement to our duty. It must be as that which is graven on the palms of our hands, always before our eyes. See Pro_7:1-3.
It is also intimated that we must never be ashamed to own our religion, nor to own ourselves under the check and government of it. Let it be written on our gates, and let every one that goes by our door read it, that we believe Yahweh to be Yahweh alone, and believe ourselves bound to love Him with all our hearts
