'Tend' in the Bible

For my rock and my bulwark art Thou, For Thy name's sake lead me and tend me.

They do not hunger, nor thirst, Nor smite them doth mirage and sun, For He who is pitying them doth lead them, And by fountains of waters doth tend them.

He saith to him again, a second time, 'Simon, son of Jonas, dost thou love me?' he saith to him, 'Yes, Lord; thou hast known that I dearly love thee;' he saith to him, 'Tend my sheep.'
