'Oaks' in the Bible

He will take his stand against all the cedars of Lebanon, against the proud and self-exalting; and against all the oaks of Bashan;

you who burn with lust among the oaks, under every spreading tree, who slaughter your children in the ravines, under the clefts of the rocks?

to provide for those who grieve in Zion to bestow on them a crown of beauty instead of ashes, the oil of gladness instead of mourning, a mantle of praise instead of a spirit of despair." "Then people will call them "Oaks of Righteousness", "The Planting of the LORD", in order to display his splendor.
