Matthew 23:16

ὀμόσῃ ἐν τῷ ναῷ. In classical Greek the thing on which the oath is taken is in the accusative or genitive with κατά. (τι or κατά τινος.) ναός, the ‘holy place,’ not as in A.V. the temple.

ἐν τῷ χρυσῷ τοῦ ναοῦ, i.e. the offerings made to the Temple, called ‘Corban,’ or ‘devoted;’ the use of that word made an oath binding, see ch. Matthew 15:5. Tacitus (Hist. Matthew 23:8) says of the Temple at Jerusalem: ‘illic immensæ opulentiæ templum.’
