Where in the constitution can you find the provision of 1808

In the 13th amendment

Explanation:

The Constitution that the delegates proposed included several provisions that explicity recognized and protected slavery.  Without these provisions, southern delegates would not support the new Constitution--and without the southern states on board, the Constitution had no chance of being ratified.  Provisions allowed southern states to count slaves as 3/5 persons for purposes of apportionment in Congress (even though the slaves could not, of course, vote), expressly denied to Congress the power to prohibit importation of new slaves until 1808, and prevented free states from enacting laws protecting fugitive slaves.
