wholly of blue - Compare Exodus 25:4 note. The third and external covering of the ark only was to be of this color. The table of showbread had Numbers 4:8 an outer wrapping of scarlet; the altar Numbers 4:13 one of purple.
Put in the staves - Probably, “put the staves in order.” These were never taken out of the golden rings by which the ark was to be borne (see Exodus 25:14-15), but would need adjustment.
