Holman Bible Dictionary [3]

 Exodus 28:36 Numbers 16:38

International Standard Bible Encyclopedia [4]

plat  : A term seemingly not used in the Bible for a dish as it is so commonly used at present, but always for a tablet or sheet of metal. (1) ציץ , cı̄c (  Exodus 28:36;  Exodus 39:30;  Leviticus 8:9 ), a plate of gold on the front of the mitre of the high priest. The name seems to have been given because of the radiance of the object. (2) פּח , paḥ ( Exodus 39:3;  Numbers 16:38 ), of plates or sheets of metal produced by hammering. (3) לוּח , lūaḥ , used for tablets or tables of stone ( Exodus 24:12 , etc.), but in  1 Kings 7:36 for the metal plates on the bases of the lavers in the temple. The word סרן , ṣeren , is rendered "plate" in  1 Kings 7:30 the King James Version, manifestly incorrectly, the Revised Version (British and American) "axle."
