'Lay Aside' in the Bible

If I say, I will forget my complaint, I will lay aside my sad countenance, and brighten up,

Lay aside simplicity and live; walk in the way of understanding."

Then all the princes of the sea shall come down from their thrones, and lay aside their robes, and strip off their broidered garments: they shall clothe themselves with trembling; they shall sit upon the ground, and shall tremble every moment, and be astonished at thee.

When the priests enter [the Holy Place], they shall not go out from the sanctuary into the outer court unless they lay there their garments in which they minister, for these are holy (set apart). They shall put on other garments before they approach that which is for the people.”
