how can the mute confess the Word?

I woke up in the middle of the night at 400am last night & this question just popped in my head, "How does the mute speak". How is he going to confess his healing, his blessings...
Immediately I turned on my computer & looked for the Greek translation for the word 'say' Pastor mentioned in Mark 11:23.

For^{1063 verily281 I say3004 unto you,5213 That3754 whosoever3739, 302 shall say2036 unto this5129 mountain,3735 Be thou removed,142 and2532 be thou cast906 into1519 the3588 sea;2281 and2532 shall not3361 doubt1252 in1722 his848 heart,2588 but235 shall believe4100 that3754 those things which3739 he saith3004 shall come to pass;1096 he846 shall have2071 whatsoever3739, 1437 he saith.2036}
G3004 leg'-o
A primary verb; properly to "lay" forth, that is, (figuratively) relate (in words [usually of systematic or set discourse; whereas G2036 and G5346 generally refer to an individual expression or speech respectively; by implication to mean: - ask, bid, boast, call, describe, give out, name, put forth, say (-ing, on), shew, speak, tell, utter.
G2036 ep'-o
A primary verb (used only in the definite past tense, to speak or say (by word or writting): - answer, bid, bring word, call, command, grant, say (on), speak, tell. Compare G3004.

Definition from Greek Lexicon

to say before to say in what precedes, to say above to say before i.e. heretofore, formerly to say beforehand i.e. before the event: prophecies

What really caught my attention most & gave me the 'answer' was the mentioned of, 'to speak by writing.'
The meaning of discourse mentioned in G3004 is actually a spoken or written communication between people. You see here & also used in G2036 that speech & writing is interchangeable.
The deaf hear not, but he is able to read the writings of Jesus. The mute speak not, but they are able to write the words of Jesus.
I did ask him once, why then ask us to write our vision down & it'll come to pass & also speak. which? (went to look at the verse with vision)...my reaction was....omg!! check it out.
Hab 2:2 And the LORD answered me, and said, Write the vision, and make it plain upon tables, that he may run that readeth it.
Hab 2:3 For the vision is yet for an appointed time, but at the end it shall speak, and not lie: though it tarry, wait for it; because it will surely come, it will not tarry.
This bring to rememberance a card I saw at Joan's place on her keyboard recently when I went to her place to learn. It was made abt ten years ago when she had not joined music min. It was the words of David being a talented musician written in Samuel. There were also two pics of her as a young little girl playing piano & flute. And this small 'poster' is always placed on her keyboard till today even when she practised! How the word written speaks for itself now. Amazing when I saw it. It makes me want to start writing now=)
I love how Strong’s & Greek Lexicon explains it. A definite past tense. A prophecy. Sounds like it’s sure to happenedJ
I love it how he shows me as I write each time. Something about writing;)

He told me to look up the word readeth in Habakkuk 2:2 as I woke up this morning. And to my suprised, it is translated in Hebrew in BDB as:

1) to call, call out, recite, read, cry out, proclaim
1a) (Qal)
1a1) to call, cry, utter a loud sound
1a2) to call unto, cry (for help), call (with name of God)
1a3) to proclaim
1a4) to read aloud, read (to oneself), read
1a5) to summon, invite, call for, call and commission, appoint, call and endow
1a6) to call, name, give name to, call by
1b) (Niphal)
1b1) to call oneself
1b2) to be called, be proclaimed, be read aloud, be summoned, be named
1c) (Pual) to be called, be named, be called out, be chosen

I see the word call out/forth more than read. cool eh? I always read it as 'read'.
Write your vision down, when you see it, speak it. Surely it'll come forth in its perfect time.
