Leviticus 15:12

15:12 A clay vessel which the man with the discharge touches must be broken, and any wooden utensil must be rinsed in water.

Leviticus 26:19

26:19 I will break your strong pride and make your sky like iron and your land like bronze.

tn The Hebrew term כְּלִי (kÿli) can mean “vessel” (v. 12a) or “utensil, implement, article” (v. 12b). An article of clay would refer to a vessel or container of some sort, while one made of wood would refer to some kind of tool or instrument.
