This term appears in Genesis 30:37, describing Jacob's selective breeding technique: 'exposing the white which was in the rods.' Jacob peeled bark from poplar branches to create white stripes, then placed these rods before breeding flocks. The word describes the act of laying bare or uncovering what lies beneath the surface. Whether this reflected ancient animal husbandry theory or folkloric practice, the text presents Jacob deliberately exposing contrasting colors. The 'exposing of the white' was central to his strategy for increasing his flock's proportion of striped offspring.
