How was Muhammad mentioned by name in the Old Testament? I’ve heard this claim a lot, but can somebody clarify what this claim exactly is?

The claim is that Muhammad is mentioned by name in the Song of Songs 5:16

Song of Solomon 5:16 - His mouth is most sweet: yea, he is altogether lovely. This is my beloved, and this is my friend, O daughters of Jerusalem. The word for altogether lovely looks like a Hebrew version of MuhammadIM

The context is the wife of Solomon describing her beloved to the daughters of Jerusalem (in Solomon’s harem)

But the claim is false, there is a word, an adjectival noun, which means “the desired” and this word comes from the verb root CHAMAD (Khet - Mem - Dalet) which means to desire, covet or lust after. My adding the prefix M (Mem) it becomes the word MACHMAD - it turns the verb into an adjectival noun.

The Hebrew word LOOKS LIKE Muhammad, but it is the wrong letters.
Muhammad in Hebrew would be MEM - HEY - MEM - DALET

This word is MEM - KHET - MEM - DALET with a laryngeal KHET instead of the aspirated HEY, and the word has a superlative suffix of YOD - MEM - (im) which makes it MACHMADIM. There is another word in the same verse meaning SWEET - MAMTAQ, it too has a superlative IM so the word is MAMTAQIM which means MOST SWEET, in the same way MACHMAD means “the desired, or desirable” when IM is added to get MACHMADIM it means THE MOST-DESIRED

Add to this the previous word KOLE (All) you get ALL(of) MOST-DESIRED which is translated as “altogether lovely” in the KJV.

The verb CHAMAD and it’s other forms like MACHMAD appear 40 times in the Old Testament and in every case it is to do with desiring (CHAMAD appears in the Ten Commandments as do not covet - lust after) and it is a normal Hebrew word, used with normal Hebrew grammar.

Because it looks similar to Muhammad Muslims jump through hoops to explain away the IM ending by claiming a “plural of respect” which is nonsense, plurals of respect are used in PRONOUNS - Such as God saying “Let us” do something.

No mention is made either, of the KHET - HEY difference.
