"And you shall offer the passover sacrifice to the Lord your God, from the flock or the herd, at the place which the Lord will choose, to make his name dwell there . . . 7 And you shall boil it and eat it at the place which the Lord your God will choose; and in the morning you shall turn and go to your tents.
"But when you go over the Jordan, and live in the land which the Lord your God gives you to inherit, and when he gives you rest from all your enemies round about, so that you live in safety, 11 then to the place which the Lord your God will choose, to make his name dwell there, thither you shall bring all that I command you: your burnt offerings and your sacrifices, your tithes and the offering that you present, and all your votive offerings which you vow to the Lord" (Deut 12:10-11)
Jub. 49:16-17: “And it is not fitting to eat [the Passover] outside of the sanctuary of the Lord, but facing the sanctuary of the Lord. And all the people of the congregation of Israel will observe it in its (appointed) time.
11Q19 17:8-9: [Concerning the Passover Meal]: And they shall consume it [atnight] 9 in the courtyards of [the] sanctuary
Yet, as is abundantly clear from other texts we know in fact that the Passover was not eaten by Jews in the Temple.
Philo, Special Laws, 2.146, 147-149: [in the first Passover] they sacrificed at that time themselves out of their exceeding joy, without waiting for priests… (147) But those who are in the habit of turning plain stories into allegory, argue that the passover figuratively represents the purification of the soul... (148) And each house is at that time invested with the character and dignity of a temple, the victim being sacrificed so as to make a suitable feast for the man who has provided it and of those who are collected to share in the feast, being all duly purified with holy ablutions…
 Joachim Jeremias, The Eucharistic Words of Jesus (3d ed.; London: SCM, 1966) 43, n. 2;55, 75; idem., Jerusalem in the Time of Jesus (rev. ed.; London: SCM, 1969), 115-16.; Gustaf Dalman, Jesus-Jeshua (London: S.P.C.K., 1929) 93-95. This, of course, has huge implications for understanding the Gospel accounts of the Last Supper, where Jesus very clearly eats a meal within the city, though he apparently retires to a place outside of it (Bethany prior to feast, cf. John 12:1; cf. Mark 11:11 and the Mount of Olives afterwards, cf. Jn 18:1; Matt 26:30). Such actions only make sense if Jesus was eating the Passover. But I digress...
