§ 207. XIII. Another rule of interpretation deserves consideration in regard to the constitution. There are certain maxims, which have found their way, not only into judicial discussions, but into the business of common life, as founded in common sense, and common convenience. Thus, it is often said, that in an instrument a specification of particulars is an exclusion of generals; or the expression of one thing is the exclusion of another. Lord Bacon's remark, "that, as exception strengthens the force of a law in cases not excepted, so enumeration weakens it in cases not enumerated," has been perpetually referred to, as a fine illustration.
Justice Joseph Story on Rules of Constitutional Interpretation
1833 It is a general principle of statutory construction that the mention of one thing implies the exclusion Of another. (For an exhaustive annotation on this "rule of exclusion," see: 73 Am. Jur. 2d Statutes §212 and the citations collected thereunder.) As exceptions in a statute strengthen the force of law in cases not excepted, so enumerations weaken it in cases not enumerated.
John C. Danforth, Missouri Attorney General, April 21, 1975
the familiar principle laid down in Page vs. Allen, 58 Pa. 338, 346, that "as exceptions strengthen the force of a general law, so enumeration weakens, as to things not enumerated."

------
Above you have THREE linked quotes from legal authorities stating that if something is NOT enumerated in the Constitution, then the case for it is weakened.
Now....please show me where in the Constitution are the PROVISIONS for secession?
You were asked to provide Constitutional sanction for secession. You failed miserably to provide even a shred of evidence that secession is sanctioned by it.
“Now....please show me where in the Constitution are the PROVISIONS for secession?”
There are none, as secession is not a legal option.
