'Set Apart' in the Bible

Then Abraham set apart seven ewe lambs of the flock,

and Abimelech said to Abraham, “What is the meaning of these seven ewe lambs which you have set apart?”

The blessings of thy father, have prevailed, Over the blessings of the perpetual mountains, The charm of the age-abiding hills, - They turn out to be, for the head of Joseph, And for the crown of the head of him who was set apart from his brethren.
