And last but not least (sorry for all the posts!), there's
this article about a mysterious letter addressed to Chaim eight years after his murder, and cryptic Hebrew markings left on Chaim's grave.
In regards to the letters, they appear to be the Hebrew letters Y-TS-F. Now, Hebrew is a language whose words are composed of (usually) three-consonant roots, and it's written without vowels.
According to biblehub, this root in particular means "to look out" or "keep watch."
However, the root word in this particular configuration
occurs only once in the Bible according to Biblehub, at Genesis 31:49, which reads, "May the Lord
watch between you and me, when we are out of sight of each other." To me, this verse out of context could be read as a prayer for the dead, since obviously Chaim is "out of sight" of all of us. In context, it relates to a pact made between Jacob and his uncle Laban, using a mound of stones, and this word was carved by the mound of Chaim's grave.
But—and this may be farfetched—Genesis 31:49 would have been in the last section of the Torah portion read on the Sabbath closest to Chaim's (secular) 13th birthday, after his bar-mitzvah.
According to
this article, Chaim was buried on Sunday, November 2, 1986, " just two weeks short of his 16th birthday." This means he would've been born in mid-November 1970. Now, granted, the bar-mitzvah ceremony is calculated according to the Hebrew calendar, not the secular. But is it a coincidence that this verse appears in the final Torah portion read near his 13th secular birthday, and
this article says "it is traditional for the bar/bat mitzvah to read the final portion" during the ceremony?
