To wrap up, to fold together — used of an unformed mass or embryo. This rare word appears in one of the most profound passages about divine foreknowledge and human formation in the womb.
The single use of galam in Psalm 139:16 ('Your eyes saw my unformed substance') is theologically explosive. It teaches that God knew and valued each person before they had recognizable form. The word captures the mystery of divine intentionality — God doesn't wait for completion to begin loving. He sees the finished masterpiece while it's still an unformed lump.
