The remembrance (Zech 6:14-6:14)

“The crown

Shall be in the care

Of Heldai,

Tobijah,

Jedaiah,

With Josiah,

The son of Zephaniah,

As a memorial

In the Temple of Yahweh.”

Those returning captives mentioned earlier, Heldai, Tobijah, Jedaiah, and Josiah were to take care of this crown.  It would be in the Temple of Yahweh as a reminder or memorial of their former captivity.
