Ezekiel 34:11-12,14-16:

For thus says Sovereign YHWH: I myself will search for my sheep; I will seek them out. As shepherds seek out their flocks when their flocks are scattered in every direction, so I will search for my sheep and rescue them, I will feed them on good pasture land, and the mountain heights of Israel will be their grazing ground. I myself will tend my flock and have it lie down, thus says Sovereign YHWH. I will seek out the lost, I will return the strayed, I will bind up the injured, and I will strengthen the weak, and I will watch over the fat and the sleek. I will be a true shepherd to them.
