||Make a copper washstand along with a copper base for it. Place it between the altar and the Communion Tent, and fill it with water for washing.
Ve'asita kiyor nechoshet vechano nechoshet lerachtsah venatata oto beyn-Ohel Mo'ed uveyn hamizbe'ach venatata shamah mayim.
||Aaron and his sons must was their hands and feet from [this washstand].
Verachatsu Aharon uvanav mimenu et-yedeyhem ve'et-ragleyhem.
Kiyyor in Hebrew. It looked like a large kettle with two spigots for washing (Rashi; Maaseh Choshev 6:8; Yoma 37a). According to others, it was apparently like a basin with spigots (Radak, Sherashim, who says it was like a cuenca, Spanish for basin). It was later made with 12 spigots (Yoma 37a). See 1 Samuel 2:14.
(Targum; Rashi; Ibn Janach; Radak, Sherashim). Kan in Hebrew. See 1 Kings 7:38, 2 Chronicles 4:14 (cf. Ibn Ezra). In shape, the base was somewhat like an inverted pot (Tosafoth, Zevachim 22a, s.v. Kal VeChomer; Maaseh Choshev 6:9), or like an open box (Tosafoth). Some say that it was 3 handbreadths (9') high (Rabbenu Meyuchas).
Later, this base was made to include a mechanism to fill the washstand with water (Yad, Beth HaBechirah 3:18), as well as machinery to lower the entire washstand into a well (Raavad ibid.; Yoma 37a; Zevachim 20a; Yad, Biyyath HaMikdash 5:14). A similar mechanism may have existed in the Tabernacle (see Torah Sh'lemah 38:6).
