In Paleo Hebrew was drawn as a Sword. Sword shows up throughout the books of (22) Amos, (44) Acts and (66) Revelation. By studying Sword in these books all of Tä's meanings can be learned.

In Amos Tä is _____

Yahvah with Joshua (6 Joshua 1:5)
To be with someone and never leave them is to be nailed to them.

In Acts Tä is _____

Leader of the assembly (28 Ecclesiastes 1:1)
Solomon is the leader of the assembly in Ecclesiastes (sometimes translated preacher or teacher). Given we had an assembly at the end of Joshua and we are dealing with vav the word "assembly" seems closest to what's meant. The assembly is a connected group of people with the leader matched or connected to the group as it's leader.

In Revelation Tä is _____

Following Christ (50 First Corinthians 1:12)
Some follow Paul, some follow Apollos, and some follow Peter, but following Christ is best. Paul nails what matters in the discussion of following, which is who you follow. Throughout First Corinthians this is the pattern. Paul gives a list, sometimes with only two items, then nails (specifies) what is best.

Summary

Tä is:

  • end
  • last
  • contract
  • covenant

Jesus

Jesus is the Tä.

66 Revelation 1:8
8I am Wa and Ta, the beginning and the ending says Master God, who is and who was and who is to come, the Almighty.

Again.

66 Revelation 21:6
6And he said to me, I am Wa and Ta, the beginning and the end. I will freely give of the fountain of living water to him who is thirsty.

And again.

66 Revelation 22:13
66 13I am Wa and Ta, the beginning and the end, the first and the last.

He's also the Sword.

52 Ephesians 6:17
17Put on the helmet of salvation and take the sword of the Spirit, which is the word of God;

We know Jesus is the "Word of God" from various places, so when the "Word of God" is defined as the "Sword of the Spirit" it's another name or reference for Jesus.

54 Hebrews 4:12-13
12For the word of God is living and powerful, and sharper than any 2-edged sword, piercing even to the point of division between soul and spirit, and between the joints and marrow and bones, and is a discerner of the thoughts and intents of the heart.
13And there is no creature hidden from his sight; but all things are naked and open before the eyes of him to whom we are to answer.

Note how the "sword" in this verse is a "he." The "he" is a reference to the "sword" and "Word of God" in verse 12. Some translations add a "God" at the beginning of verse 13, but there's no God in the Aramaic, just a "he."
