There aren’t ten. And there is no agreement on which ten of the many are “the” ten. The phrase “ten commandments” appears in Exodus 34 and in Deuteronomy 10, which is a reference but not a list. The strange thing is that the line about Moses writing on the (new) tablets “the ten commandments” is preceded by a list of totally different orders, such as “you shall keep the feast of the unleavened bread”. The familiar list is given earlier in Exodus 20, except that it is never there called “the Ten Commandments” and there is no mention of tablets until 11 chapters and 600-some commandments later.
Also, Exodus 20 gives thirteen specific orders, not ten. The same list is repeated in Deuteronomy 5, yet again not called “Ten Commandments”. Wikipedia offers this helpful table showing how seven different Abrahamic faiths carve up the “Ten Commandments”.
