'Tend' in the Bible

but David went back and forth from Saul to tend his father’s flock at Bethlehem.

Like a shepherd He will tend His flock,In His arm He will gather the lambsAnd carry them in His bosom;He will gently lead the nursing ewes.

I will also raise up shepherds over them and they will tend them; and they will not be afraid any longer, nor be terrified, nor will any be missing,” declares the Lord.
