'Shepherd's' in the Bible

My sojourning hath departed, And been removed from me as a shepherd's tent, I have drawn together, as a weaver, my life, By weakness it cutteth me off, From day unto night Thou dost end me.

As a shepherd's searching of his drove, In the day of his being in the midst of his scattered flock, so I do seek My flock, And have delivered them out of all places, Whither they have been scattered, In a day of cloud and thick darkness.
