The Pharaohs of Ancient Egypt were not accustomed to receiving commands from others, particularly from such "lowly" people as Moses and Aaron. Their message came directly from The God Of Creation, but the Pharaoh was of no mind to listen. But then, the Pharaohs didn't believe in the True God - their "gods" were various idols, and such natural things as bulls and reptiles and the Nile River. They worshiped created things, rather than The Creator. That was the primary reason that God targeted a number of Egypt's "gods" directly with The Ten Plagues.
Daniel's 70 Weeks (490 years) gives a major clue that God determines and measures the redemptive history of Israel in Cycles of 490 years which equates to 70 Sabbatical Years.. In particular, it defines the last of these Cycles as running from the Ezra Decree to restore Jerusalem (458 BC) to Messiah's sacrificial atoning Death and Resurrection (AD 33).
Matthew 18:21,22 implies there is something special about seventy times seven times:
These prophecies fulfilled since 1948, prove that God's time piece, which He stopped in 70 AD when the Temple was destroyed in a severe judgment of God, has started ticking again, as He had announced by the pen of the prophet Daniel, in the time when Babylon was the head of gold of the gentile empires.
Jude 1:24 Now unto him that is able to keep you from falling, and to present you faultless before the presence of his glory with exceeding joy,
25 To the only wise God our Saviour, be glory and majesty, dominion and power, both now and ever. Amen.
Luke 8:4 And when much people were gathered together, and were come to him out of every city, he spake by a parable:
Galatians 5:22 But the fruit of the Spirit is love, joy, peace, longsuffering, gentleness, goodness, faith,
23 Meekness, temperance: against such there is no law.
The Bible speaks of "bad trees" producing "bad fruit" as evidence of non-conversion, whereas "good trees" produce "good fruit" as evidence that the Holy Spirit has regenerated that person.
