'Tended' in the Bible

My anger burns against the shepherds,so I will punish the leaders.For the Lord of Hosts has tended His flock,the house of Judah;He will make them like His majestic steed in battle.

So I began to shepherd the flock destined for slaughter, the most afflicted of all the flock. Then I took two staffs, calling one "Pleasantness" and the other "Binders," and I tended the flock.
