The Meaning of Numbers: The Number 126
The possible meaning of the number 126 is derived from the occurrence of certain words in the original language of the Old Testament.
Two words occur 126 times in the Bible. The Hebrew koach (Strong's Concordance #H3581) represents the ability of something to convey strength, power, might or produce wealth. Its first use is in Genesis 4 as part of God's punishment of Cain for killing his innocent and righteous brother Abel.
When thou tillest the ground, it shall not henceforth yield unto thee her strength (koach); a fugitive and a vagabond shalt thou be in the earth (Genesis 4:12, KJV).
The word koach, rather surprisingly, is also translated (only once) as "chameleon." It is listed as one of the animals God considers unclean or unfit for human consumption.
And the ferret, and the chameleon (koach), and the lizard, and the snail, and the mole (Leviticus 11:30, KJV).
Strong's #H6106, etsem, additionally used 126 times, is a Hebrew word that is usually translated as "bone" or "body." It sometimes, however, is translated as "selfsame" in the King James. Adam uses etsem, in his first recorded words after his creation, when he is introduced to Eve!
And Adam said, This is now bone (etsem) of my bones (min etsem, meaning out of my bones or body), and flesh of my flesh: she shall be called Woman, because she was taken out of Man (Genesis 2:23, KJV).

The first chapter of Acts is the only one in Scripture that contains exactly 26 verses (126). Acts 1:26 reveals the outcome of the apostles casting lots to determine which of two men, Joseph or Matthias, would take the place of Judas Iscariot as one of the twelve apostles.
Then they cast their lots; and the lot fell on Matthias, and he was numbered with the eleven apostles (Acts 1:26, HBFV).
The Psalms and Number 126
The writer of Psalm 126, speaking for those who returned from exile, remembers the joy they felt when the Lord brought them back.
When the Lord brought back the exiles, those who returned to Zion, we were like those who dream. Then our mouth was filled with laughter, and our tongue with singing; then they said among the nations, "The Lord has done great things with them." . . .
Those who sow in tears shall reap in joy. He who goes forth and weeps, bearing precious seed, shall doubtless come home with rejoicing, bringing his sheaves with him (verses 1 - 2, 5 - 6 of Psalm 126, HBFV).
