Isaiah 1:29-31 is spoken to the people of Judah and Jerusalem. It is probably God speaking.

## the sacred oak trees...gardens ##

These phrases refer to places where the people of Judah worshiped idols.

## embarrassed by ##

"disgraced because of"

## For you will be like an oak whose leaf fades, and like a garden that has no water ##

The people who were worshiping false gods were being compared to a tree or garden that is dying because it is cut off from what gives it life. (See: [[rc://en/ta/man/translate/figs-simile]])
