Deuteronomy 28:40

Thou shalt have olive trees throughout thy coasts ,.... In the several parts of the land of Canaan, which is therefore called a land of olive oil, Deuteronomy 8:8 ,

but thou shalt not anoint thyself with the oil ; nor any other relations, friends, guests, as was usual at entertainments; see Psalm 23:5 ; for the phrase "thyself" is not in the text. The reason why they should not anoint is, because they would have no oil to anoint with:

for thine olive shall cast his fruit ; before it is ripe, by one means or another, as by winds, or blasting and mildew; see Amos 4:9 .
