Though they offer sacrifice, immolate flesh and eat it, the LORD is not pleased with them. He shall still remember their guilt and punish their sins; they shall return to Egypt. (Hos 8:4-7, 11-13)
At the sight of the crowds, his heart was moved with pity for them because they were troubled and abandoned, like sheep without a shepherd. (Mt 9:32-38)

“They shall return to Egypt” is a figurative way of saying they will be held captive and become slaves again, negating the salvation the Lord won for them. But God has compassion on us in sending us the Good Shepherd.
