Reading the books of Lev and Deut, I note that in Exodus and Levit there are very many instruction given to the Hebrews and their hangers on regarding their worship, and their movable Temple. All of this was whilst they were a nomadic group, however, once they prepared to enter the land promised to them and were to commence a settled existence the instructions were coalesced into those in Deut.
To me this means that the instructions in the second teaching (Deut) are the ones Jesus ( Yeshua) was talking about when he said "not one jot or the old law will be changed". Accepting this cuts the 600+ Jewish Laws down to a number that are not burdensome (1 John 5;3 et seq)
Am I on a correct track?
Thank you for that great question. You're clearly thinking, and you're almost on the right track, but there is more to it.
Truth is, every command YHWH ever handed to His people was for good reason, but He never revoked any. It's just as my article stated: Most of those "613 commands in the wilderness times were for the Levite priests; some were only for men while others only for women; some were only for a certain point in time; some for Nazirite vows, and 200+ related to the Temple which is not standing to this day (but will be in the future, and the sacrifices will resume – please see my articles: (https://therefinersfire.org/original_commandments1.htm) and https://therefinersfire.org/third_temple.htm).
People also don't realize that the “numbering” of the 613 Mitzvot (Commandments) were more of a man-made tradition rather than an actual "number of commandments" sent down by YHWH. The idea originated in the Talmud which says there are both "positive" and "negative" mitzvot (do's and don'ts) which can be divided into 365 Negative Mitzvot (to remind us not to do bad things every day of the year) plus 248 Positive Mitzvot - for a total of 613).
Similarly, the tzit-tzit (knotted fringes) of the tallit (prayer shawl) are also connected to the 613 commandments. Torah commentator Rashi declared that the number of knots on a tzit-tzit (in its Mishnaic spelling) has the value of 600. When doubled over, each tassel has eight threads and five sets of knots, which totals 13 - for a grand total of 613. This concept reminds tallit wearers of all Torah commandments. (That particular way of tying tzitzit is done by the Ashkenazi Jews.)
IF traditional Jews thought those commands were irrelevant after the Hebrews were sent into the Land, why would they still tie the knots the way they do?
And take a look at this passage:
Matthew 22:36. "Teacher, which Commandment in Torah is the greatest?" 37. And Y'shua said to him, that "You should love Master YHWH your Elohim with all your heart and with all your soul and with all your might and with all your mind." 38. This is the first and the greatest Commandment. 39. And the second is like it. That "You should love your neighbor as yourself." (AENT)
UNFORTUNATELY, many people stop right there, TOTALLY IGNORING verse 49, which says: “On these two commandments hang Torah and the prophets.”
The Torah and the Prophets HANG/ARE DEPENDENT ON those two commands!
So you see, there's more to it than just "loving God and loving your neighbor,” or trying to figure out ways to circumvent YHWH’s original Divine Instructions. SIN is still sin and God still expects His people to adhere to His Divine Standards for moral, holy living! So, it is important to note that neither YHWH nor His Divine Messiah ever said that the original Torah commands were to be replaced, abolished or somehow consolidated!
