wash them with water
29:4 wash them with water. There are frequent references in the Mosaic writings to the importance of washing, especially for the priests who were continually handling and slaying the sacrificial animals. See also Exodus 19:10; Numbers 19:7,8,11; Leviticus 14:47,51; Exodus 40:31,32; etc. These various washings not only had ritualistic and spiritual significance, but also important hygienic benefits. The value of washing and bathing was not fully appreciated by most other nations until modern times. The practical value of “sprinkling the unclean...to the purifying of the flesh” is intimated in Hebrews 9:13.
