What, and Who, are Angels? In the 3 languages of the Bible, Hebrew, Aramaic, and Greek, There are 2 major words and one minor in Hebrew. The KJV translates the minor Hebrew, shin’an as “angels”. Ps 68:17 reads: “The chariots of God are twenty thousand, even thousands of angels: the Lord is among them, as in Sinai, in the holy place.” This is a mistranslation as the true meaning is repetition
repetitions, twice-told repetition, twice ten thousands, thousands of repetitions, twice-told thousands
myriads (in effect). According to Strong’s Concordance.

Ps 68:17 “Verse 17. The chariots of God are twenty thousand ribbothayim alpey shinan, "two myriads of thousands doubled." Does not this mean simply forty thousand? A myriad is 10,000; two myriads, 20,000; these doubled, 40,000. Or thus: 10,000 + 10,000 + 20,000 = 40,000. The Targum says, "The chariots of God are two myriads; two thousand angels draw them; the majesty of God rests upon them in holiness on Mount Sinai." But what does this mean? We must die to know.” (Adam Clarke Commentary)

The other words, both Hebrew and Aramaic are Mal’ak ( mal-awk'). Variously translated as:
1. messenger, representative
a. messenger
b. angel

KJV Mal'ak (214) - ambassadors, 4; angel, 111; messenger, 98; variant 1;

NASB (213) - ambassadors, 3; angel 101; angels 9; envoys, 1; messenger, 24; messengers, 76;

Mal'ak (Aramaic) angel, only 2 times in Daniel 3:28, 6:22 (from their God) in both KJV and NASB.

Easton’s Bible Dictionary says; “A word signifying, both in Hebrew and Greek, a ‘messenger,’ and hence employed to denote any agent God sends to execute his purposes.” “But its distinctive application is to certain heavenly intelligences whom God employs in carrying on his government of the world. The name does not denote their nature but their office as messengers. (Easton’s Bible Dictionary, 1894, pg 42)

Some misunderstanding is shown in Easton’s Bible Dictionary, 1894, pg 42, “It is also applied to such impersonal agents as the pestilence (2 Sam. 24:16, 17; 2 Kings 19:35), Ps. 104:3, 4), the wind. In reading these scriptures, we find; “And the angel kept his hand thrust out toward Jerusalem to bring it to ruin; and Jehovah began to feel regret over the calamity, and so he said to the angel that was bringing ruin among the people: ‘It is enough! Now let your hand drop.’ And Jehovah’s angel himself happened to be close by the threshing floor of Araunah the Jebusite. And David proceeded to say to Jehovah, when he saw the angel that was striking the people down, yes, he proceeded to say; ‘Here it is I that have sinned and it is I that have done wrong; but these sheep—what have they done? Let your hand please, come upon me and upon the house of my father.’” (2 Sam. 24:16, 17 NWT)

“And it came about on that night that the angel of Jehovah proceeded to go out and strike down a hundred and eighty-five thousand in the camp of the Assyrians. When people rose up early in the morning, why, there all of them were dead carcasses.” (2 Ki 19:35 NWT)

Do those two scriptures read and sound like “impersonal agents” of pestilence? Or, “. . . Making the clouds his chariot, Walking upon the wings of the wind, Making his angels spirits, His ministers a devouring fire.” (Ps 104:3, 4 NWT), like the wind?

Psalm 104 is a song, with words that are metaphors. In the Hebrew translation, it uses one word for wind and spirit; ruwach (roo'-akh) = wind, breath, mind, spirit. The angels = Mal'ak (Strong’s Hebrew Dictionary)

In the Septuagint translation, it uses two different words, “Walking upon the wings of the wind,”; the word is anemos (an’-em-os). We have an English word which comes from this: Animate. There is a song titled “Ride Like the Wind”, which has a line, “I’ve got to ride, ride like the wind, to be free again.” The other word is pneuma (pnyoo'-mah); a current of air, i.e. breath (blast) or a breeze; by analogy or figuratively, a spirit, i.e. (human) the rational soul, (by implication) vital principle, mental disposition, etc., or (superhuman) an angel, demon, or (divine) God, Christ's spirit, the Holy Spirit:--ghost, life, spirit(-ual, -ually), mind.
