At the tower of Babel, the people are scattered and many languages emerge
And the Lord said, Behold, the people is one, and they have all one language; and this they begin to do: and now nothing will be restrained from them, which they have imagined to do. [7] Go to, let us go down, and there confound their language, that they may not understand one another’s speech. [8] So the Lord scattered them abroad from thence upon the face of all the earth: and they left off to build the city.
Genesis 11:6-8
God makes a promise: For then I will restore to the peoples a pure language, That they all may call on the name of the LORD, To serve Him with one accord. – Zephaniah 3:9
God said he will restore to the people a pure language.
The whole earth, at the time of the tower of Babel, was of one language, but this ‘one language’ is not just a reference to Spanish, English French etc but it refers to the people’s focus / ideas / goals were in agreement for folly, ‘speaking one language of foolishness / vain things’.
They weren’t speaking the pure language of God.
What is God’s pure language, which they weren’t speaking?
Psalm 119:140 Thy word is very pure: therefore thy servant loveth it.
Psalm 19:8 The statutes of the Lord are right, rejoicing the heart: the commandment of the Lord is pure, enlightening the eyes.
Psalm 12:6 The words of the Lord are pure words: as silver tried in a furnace of earth, purified seven times.
The promise fulfilled?
And when the day of Pentecost was fully come, they were all with one accord in one place. [2] And suddenly there came a sound from heaven as of a rushing mighty wind, and it filled all the house where they were sitting.
[3] And there appeared unto them cloven tongues like as of fire, and it sat upon each of them. [4] And they were all filled with the Holy Ghost, and began to speak with other tongues, as the Spirit gave them utterance.
[5] And there were dwelling at Jerusalem Jews, devout men, out of every nation under heaven. [6] Now when this was noised abroad, the multitude came together, and were confounded, because that every man heard them speak in his own language.
Acts 2:1-6
To me, there seems to be a clear connect between the tower of Babel and the day of Pentecost. Feel free to chime in
