2 Maccabees 2:7
5 Jeremiah came and found a cave-dwelling, and he brought there the tent and the ark and the altar of incense; then he sealed up the entrance. 6 Some of those who followed him came up intending to mark the way, but could not find it. 7 When Jeremiah learned of it, he rebuked them and declared: "The place shall remain unknown until God gathers his people together again and shows his mercy. 8 Then the Lord will disclose these things, and the glory of the Lord and the cloud will appear, as they were shown in the case of Moses, and as Solomon asked that the place should be specially consecrated." 9 It was also made clear that being possessed of wisdom Solomon offered sacrifice for the dedication and completion of the temple.
Ambrose On the Duty of the Clergy 3.17
101 Jeremiah coming to a spot found there a house like a cave, and brought into it the tabernacle, the ark, and the altar of incense, and closed up the entrance. And when those who had come with him examined it rather closely to mark the spot, they could not discover nor find it. When Jeremiah understood what they wanted he said: The spot will remain unknown until God shall gather His people together and be gracious to them. Then God shall reveal these things and the majesty of the Lord shall appear.
Notes and References
"... Not all the works that were excluded from the canon were deemed heretical. Some were merely 'of the second rank' or 'among the apocrypha' (works that were 'to be hidden away' because they were not to be read, at least not in the liturgy). For most church fathers, 'the apocrypha' was not a fixed selection but a fluid category for books of dubious status. In modern parlance, the phrase 'the Apocrypha' (or 'the Apocrypha of the Old Testament') is often used to designate those Jewish books (Ben Sira, Wisdom of Solomon, 1 Maccabees, 2 Maccabees, Judith, Tobit, etc.) that are included in the Greek or Latin Old Testament of the church but are absent from the Hebrew Tanak of the Jews ..."
