derived from a present participial form of eimi, "to be," denotes "substance, property," Luke 15:12,13 , RV, "substance," AV, "goods" and "substance."

2: ὑπάρχοντα

(Strong's #5224 — Verb — huparchonta — hoop-ar'-khon-tah )

the neuter plural of the present participle of huparcho, "to be in existence," is used as a noun with the article, signifying one's "goods," and translated "substance" in Luke 8:3 . See GOODS , POSSESS , A, No. 3.

3: ὕπαρξις

(Strong's #5223 — Noun Feminine — huparxis — hoop'-arx-is )

existence (akin to No. 2), possession: see POSSESS , B, No. 4.

4: ὑπόστασις

(Strong's #5287 — Noun Feminine — hupostasis — hoop-os'-tas-is )

for which see CONFIDENCE , A No. 2, is translated "substance" (a) in Hebrews 1:3 , of Christ as "the very image" of God's "substance;" here the word has the meaning of the real nature of that to which reference is made in contrast to the outward manifestation (see the preceding clause); it speaks of the Divine essence of God existent and expressed in the revelation of His Son. The AV, "person" is an anachronism; the word was not so rendered till the 4th cent. Most of the earlier Eng. versions have "substance;" (b) in Hebrews 11:1 it has the meaning of "confidence, assurance" (RV), marg., "the giving substance to," AV, "substance," something that could not equally be expressed by elpis, "hope."
