Not openly,— This suggests another reason for our Lord's delay. Had he taken his journey at the usual time, the multitudes who were on the road gathering round him, and accompanying him to Jerusalem, might have given fresh matter of offence to his enemies; for which reason he did not set out till the greater part of the people were gone; and then he went up not publicly, but as it were in secret; that is, he neither preached nor wrought miracles by the way, nor had any crowd attending him.
