You come from a strange land,
Borne on the weapons of a foreign foe;
This first felt wrong thou hast to wash away.
Then bear thee like a genuine son of Moscow,
With reverence due to all her usages.
Keep promise with the Poles, and value them,
For thou hast need of friends on thy new throne:
The arm that placed thee there can hurl thee down.
Esteem them honorably, yet ape them not;
Strange customs thrive not in a foreign soil.
And, whatsoe'er thou dost, revere thy mother--
You'll find a mother----

DEMETRIUS.
Oh, my liege!

KING.
High claim
Hath she upon thy filial reverence.
Do her all honor. 'Twixt thy subjects and
Thyself she stands, a sacred, precious link.
No human law o'errides the imperial power;
Nothing but nature may command its awe;
Nor can thy people own a surer pledge,
That thou art gentle, than thy filial love.
I say no more. Much yet is to be done,
Ere thou mak'st booty of the golden fleece.
Expect no easy victory!
Czar Boris rules with strong and skilful hand;
You take the field against no common man.
