'Sheep' in the Bible

I will certainly make all of you, O Jacob, come together; I will get together the rest of Israel; I will put them together like the sheep in their circle: like a flock in their green field; they will be full of the noise of men.

And the rest of Jacob will be among the nations, in the middle of the mass of peoples, like a lion among the beasts of the woods, like a young lion among the flocks of sheep: if he goes through, they will be crushed under foot and pulled to bits, and there will be no saviour.

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?
