- an angel in Jewish legend who is in charge of the "70 holy pencils." With these pencils Yaasriel constantly engraves anew on shards the Ineffable Name.
The third commandment read: "O My people of Israel, none among you shall call the name of the Lord in vain, for he who swears falsely by the name of the Lord shall not go unpunished on the great Judgement Day." Swearing falsely has terrible consequences not only for the one who does it, but it endangers all the world. For when God created the world, He laid over the abyss a shard, on which is engraved the Ineffable Name, that the abyss may not burst forth and destroy the world. But as often as on swears falsely in God's name, the letters of the Ineffable Name fly away, and as there is then nothing to restrain the abyss, the waters burst forth from it to destroy the world. This would surely come to pass, if God did not sent the angel Ya'asriel, who has charge of the seventy pencils, to engrave anew the Ineffable Name on the shard.
