'Sheep' in the Bible

I will surely assemble, O Jacob, all of thee; I will surely gather the remnant of Israel; I will put them together as the sheep of Bozrah, as the flock in the midst of their fold: they shall make great noise by reason of the multitude of men.

And the remnant of Jacob shall be among the Gentiles in the midst of many people as a lion among the beasts of the forest, as a young lion among the flocks of sheep: who, if he go through, both treadeth down, and teareth in pieces, and none can deliver.

Will the Lord be pleased with thousands of sheep or with ten thousand rivers of oil? am I to give my first child for my wrongdoing, the fruit of my body for the sin of my soul?
