400 silent years: Malachi was the last of the Old Testament prophets; he probably prophesied during the time of Nehemiah. Then from Malachi to John the Baptist is a period of 400 years during which no biblical prophet spoke or wrote – a period that came to be known as “the 400 years of silence”.
Presence of God: God first dwelt among the Israelites in the tabernacle and then in the temple that Solomon built. But God withdrew His presence from the people and His temple when Judah continued to rebel against Him. The glory of God did not return when the people returned to their land and God did not dwell in the second temple as it did in the first. He did not return till the Word became flesh, and dwelt (tabernacle) among us, and we saw His glory, glory as of the only begotten from the Father, full of grace and truth (John 1:14).
