For the day of the LORD is near upon all the heathen: as thou hast done, it shall be done unto thee: thy reward shall return upon thine own head.
God argues from the greater to the lesser: if He will not spare other nations, how can Edom escape His hand? The Lord judges all the earth without exception. Since He has resolved to execute judgment upon every nation, no one shall pass by.
AI summary
Edom stands convicted and condemned for one crime above all: violence against their brother Jacob. This ancient grudge against God's own people fills their measure; injuries to His people are affronts to God Himself, and He will take vengeance.

Commenting on Obadiah 1:10-16
The Lord's day of vengeance comes upon all the heathen round about, and Edom cannot escape in the general ruin. As they rejoiced at Jerusalem's destruction and barbarously used the Jews, so shall they be retaliated in kind; their reward returns upon their own head.
