'Checker work' in the Bible

These are the garments which they shall make: a breastpiece and an ephod [for the breastpiece] and a robe and a tunic of checkered work, a turban, and a sash. They shall make sacred garments for Aaron your brother and his sons, so that he may serve as a priest to Me.

“You shall weave the tunic of checkered work of fine linen, and make a turban of fine linen. You shall make a sash, the work of an embroiderer.
