The Meaning of Numbers: The Number 25
The number 25 symbolizes 'grace upon grace.' It is composed of 20 (meaning redemption) and five (grace) or grace multiplied (5 x 5).
And the Word became flesh, and tabernacled among us (and we ourselves beheld His glory, the glory as of the only begotten with the Father), full of grace and truth . . .
And of His fullness we have all received, and grace for grace. For the law was given through Moses, but grace and truth came through Jesus Christ (John 1:14, 16 - 17, HBFV).

The temple and number 25
Levities were required to be at least twenty-five years old before they could begin their service at the temple (Numbers 8:24). This minimum age requirement seems to have dropped to twenty from the time of David forward, likely due to the increasing amount of work required at the temple (1Chronicles 23:24, Ezra 3:8).
The number 25 plays a prominent role in Ezekiel's visions of the temple, which he saw in the twenty-fifth year of Judah's captivity (Ezekiel 40:1). There are at least five measurements within the prophetic temple that are twenty-five cubits long (40:13, 21, 25, 29 - 30).
Ezekiel is shown, in vision, 25 temple priests who are standing in the inner court of Jerusalem's temple. These men, with their backs to the temple, are performing the abominable act of worshipping the sun as it rises in the east (Ezekiel 8:15 - 17)!
Ezekiel, in a later vision, is shown the eastern gate of Jerusalem's temple. He sees twenty-five princes, who were possibly civil magistrates, whom the Lord reveals gives wicked advice and deceives the people into thinking the city is not in peril of being destroyed (Ezekiel 11:1 - 3).

In early 29 A.D., a short time before Passover, Jesus miraculously feeds 5,000 people near Bethsaida on the northeastern shore of the Sea of Galilee (John 6). At sunset the disciples, after Jesus decides to stay and pray, get in a boat to journey to Capernaum. Rowing at night, a "great wind" begins to buffet the ship and causes it, in spite of the disciples' best efforts, to be pushed near the middle of the sea (John 6:18, Mark 6:47 - 48)!
Jesus, knowing his disciples are struggling in the middle of Galilee, begins to walk on water toward the ship! Around 3 a.m. (Mark 6:48) the disciples, at a distance of 25 to 30 furlongs (3.1 - 3.7 miles or 5 - 6 kilometers) from where they left, see Christ walking toward them. The moment the Lord gets in the ship it is miraculously transported to their destination (John 6:21)!
