but only in the OT
only the four Hebrew letters of the Tetragrammaton (Yod, He, Waw and He)(YHWH)
The Hebrew language has no vowels, but were supplied by the reader and have been lost over time. The tetragrammaton has been found in the Dead Sea Scrolls and the Septuagint.
The Jewish Encyclopedia says this:
the word "YHWH" is found to occur 5,989 times in the Bible.
I'm not sure why the WTS and they disagree on the numbers.
I had been a JW for some time before it dawned on me that the tetragrammaton never appeared in the NT nor was it in any of the earliest manuscripts. Those facts are obscured by the statement "7,000 times in the Bible."

How many times do you find an explanation of why it is not in the NT?
If you notice the picture on this page, all the women have skirts/dresses on and the men are in casual clothes, the boys even in shorts!!!!. Note too that only fruits and vegetables are pictured as food. There are sailboats on the river below and the boy is flying a kite, evidently acceptable recreation in the new world.
