epistérizó: to make strongerOriginal Word: ἐπιστηρίζωPart of Speech:
I prop up, uphold, confirmDefinition:
I prop up, uphold, support, confirm, make stronger.
1991 epistērízō (from 1909 /epí, "suitably on, fitting" and 4741 /stērízō, "make firm") – properly, "prop up, uphold, support, confirm" (Souter), i.e. support (establish) in an apt, fitting way; to confirm as it builds on the Lord's previous work of faith (note the force of the prefix epi, "upon"). This process strengthens by extending the understanding that precedes, as it supports what must follow.
