Therefore thou shalt set thy face toward the siege of Jerusalem, and thine arm [shall be] uncovered, and thou shalt prophesy against it.
Ver. 7. Set thy face toward the siege of Jerusalem.] Steel thy countenance, be stern and resolute, to show that the Chaldees should be so. Thus this prophet proceedeth to write, as it were, in hieroglyphics, and to preach in emblems.
And thine arm shall be uncovered,] i.e., Thou shalt do thy work bodily; which, when soldiers and servants set themselves to do, they make bare their arms, ut fine expeditiores, for quicker despatch. Even orators also pleaded with their right arm, as Oecolampadius here noteth, stripped up and stretched out.
And thou shalt prophesy against it.] By these signs and dumb shows at least. See Ezekiel 3:26 .
