Solomon became the most famous man in the world for riches and wisdom, and the hopes of Israel were centered in him, only to be disappointed.

David and Solomon were also but mere types foreshadowing the coming of the great Deliverer.
[307]The nation of Israel degenerated and under the reign of Zedekiah, their last king, they fell into captivity to the Babylonians and they continued subject to other nations until they were finally driven out of Palestine.
[308]Moved by the holy spirit of God operating upon their minds, the holy prophets testified of the coming of this great Deliverer, both of his sufferings and of his glory that would follow; but they did not understand.

The matter was a mystery to them.

(1 Peter 1:11) Even the angels of heaven sought to look into it, but they were not permitted.
God's purpose was to keep the matter secret until his own due time to reveal the great truth.
[309]Then came Jesus, whose coming was announced by John the Baptist; and he was pointed out as the one who would take away the sin of the world.

He chose his disciples and they walked with him, and he taught them for three and a half years; yet they did not understand the great mystery.
