Manah (H4490) is a portion measured out and given — a share of food, sacrifice, or blessing. It is closely related to manah (verb: to number/apportion) and to the word manna. The portions given to Levites, priests, and festival participants all use this concept. Hannah's double portion reflects Elkanah's love (1 Samuel 1:5).
Portions in Scripture speak of providential allotment. The LORD is Israel's manah — their portion (Psalm 16:5; 119:57; Lamentations 3:24). What you receive is what God has measured out for you. This counters anxious grasping — if the LORD is my portion, I lack nothing essential. Nehemiah 8:10 connects portions with joy: send portions to those who have nothing.
