You will have olive trees throughout your territory but you will not anoint yourselves with the oil, because your olives will drop off.

and it will eat the offspring of your herd and the produce of your ground until you are destroyed, who will leave you no grain, new wine, or oil, nor the offspring of your herd or the young of your flock until they have caused you to perish.

“He made him (Israel) ride on the high places of the earth,
And he ate the produce of the field;
And He made him suck honey from the rock,
And [olive] oil from the flinty rock,

Of Asher he said,

“More blessed than sons is Asher;
May he be favored by his brothers,
And may he dip his foot in oil.
