Concise Bible Dictionary:

In the East this is the chief meal of the day; it is enjoyed in the evening when the labors of the day are over and the partakers have only rest before them (Mark 6:21; John 12:2). It is typical of the fullness of grace set forth in our Lord Jesus Christ, to enjoy which Israel were first invited, and afterward the poor and outcast were compelled to come and taste in God’s house (Luke 14:16-24). See LORD’S SUPPER. The destruction of the two beasts and their armies is spoken of as providing a supper for the birds that fly in mid-heaven (Rev. 19:17).
