There are only two places in Scripture that use 38
in this single context:
Deuteronomy 2:14 And the space in which we came from Kadeshbarnea [holy],
until we were come over the brook Zered [osier brook/wet habitat],
was thirty and eight years; until all the generation of the men of war wasted out from among the host,
as the LORD sware unto them.
John 5:1[7x7] After this there was a feast of the Jews, and Jesus went up to Jerusalem. 2 Now there is in Jerusalem by the Sheep Gate a pool, which is called in Hebrew, Bethesda ["house of mercy" or "flowing water"], having five porches. 3 In these lay a great multitude of sick people, blind, lame, paralyzed, waiting for the moving of the water. 4 For an angel went down at a certain time into the pool and stirred up the water; then whoever stepped in first, after the stirring of the water, was made well of whatever disease he had. Now a certain man was there who had an infirmity thirty-eight years. 6 When Jesus saw him lying there, and knew that he already had been in that condition a long time, He said to him, "Do you want to be made well?"
7The sick man answered Him, "Sir, I have no man to put me into the pool when the water is stirred up; but while I am coming, another steps down before me."8 Jesus said to him, "Rise, take up your bed and walk." 9 And immediately the man was made well, took up his bed, and walked. And that day was the Sabbath
38 as Hebrew letters Lamed Chet [pronounced lach or lay'-akh] form a word meaning green, fresh, new also natural force, vigor, freshness - this latter meaning expressed only once in:

Lamed 30 Chet 8 speaks to the 'heart life' - Lamed: learn, be taught, heart Chet: Life
Out of the abundance of the heart - the mouth speaks. Death and life are in the power of the tongue - and they that love it shall eat its fruit. Believe on the Word of God.
