Showq (H7785) refers to the thigh or lower leg — used for the human thigh and for the 'shoulder' or thigh portion of sacrificial animals given to the priest. In Leviticus and Numbers, the right thigh (showq hayamin) was the priest's portion, designated as holy.
The priestly thigh-portion (showq) represents God's careful ordering of worship and provision. Every peace offering included the right thigh for the priest — God embedded sustenance for the ministers of the altar directly into the sacrificial system. This is grace-in-structure: the worshiper's act of giving to God simultaneously provides for those who serve God. Paul invokes this principle: 'The Lord commanded that those who proclaim the gospel should get their living by the gospel' (1 Cor 9:14). The thigh also appears in the Jacob narrative — the angel touches Jacob's hip (yarek, related root), forever marking him with the limp of grace.
