25 I was a youth, but I am now old; yet I have not seen the righteous forsaken or his children ⌊begging for⌋ bread. Psalms 37 : 25-25 (LEB)
25 נַ֤עַר׀ הָיִ֗יתִי גַּם־זָ֫קַ֥נְתִּי וְֽלֹא־רָ֭אִיתִי צַדִּ֣יק נֶעֱזָ֑ב וְ֝זַרְע֗וֹ מְבַקֶּשׁ־לָֽחֶם׃ Psalms 37 : 25-25 (LhB)
The use of the hebrew, "before/to the face of Yahweh Elohenu [our God/ God of us]" (לִפְנֵ֛י יְהוָ֥ה אֱלֹהֵ֖ינוּ) The Hebrew evinces the idea that Yahweh would be present locally with Israel in the land, so that their actions would be performed BEFORE HIS FACE DIRECTLY. The first commandment is concerned with the setup of Yahweh being locally in the presence of Israel, in the land, in the tabernacle. The purpose of the commands is how to live with Yahweh locally, NOW THAT HE HAS SHOWN UP, SAVED YOU AND BROUGHT YOU NEAR.
More simply, the purpose of commands is how to be proteges, kids, rooming with Yahweh. It's how we are to share space with Yahweh as our roomie.
