Shemot 33:3-5

Orthodox Jewish Bible

³ Unto an Eretz zavat cholov and devash; for I will not go up in the midst of thee; for thou art an Am Kesheh Oref (stiffnecked, obstinate people); lest I consume thee in HaDerech.

⁴ And when HaAm heard these evil tidings, they mourned; and no ish did put on him his ornamental attire.

⁵ For Hashem had said unto Moshe, Say unto the Bnei Yisroel, Ye are an Am Kesheh Oref; I will come up into the midst of thee in a moment, and consume thee; therefore now put off thy ornamental attire from thee, that I may decide what to do unto thee.
