1: Αἰσθητήριον (Strong'S #145 — Noun Neuter — aistheterion — ahee-sthay-tay'-ree-on )

"sense, the faculty of perception, the organ of sense" (akin to aisthanomai, "to perceive"), is used in  Hebrews 5:14 , "senses," the capacities for spiritual apprehension. In the Sept.,  Jeremiah 4:19 , "(I am pained ... in the) sensitive powers (of my heart)."

International Standard Bible Encyclopedia [2]

sen´siz  : The translation of αἰσθητήριον , aisthētḗrion (  Hebrews 5:14 , "those who by reason of use have their senses exercised to discern good and evil"). The word means, primarily, the seat of the senses, the region of feeling; in the Septuagint of  Jeremiah 4:19 , it represents the Hebrew ḳı̄r , "the walls of the heart" (see the Revised Version (British and American)), and is used to denote the internal sense or faculty of perceiving and judging, which in   Hebrews 5:14 is regarded as becoming perfected by use or exercise (compare   Ephesians 4:12 f;   1 Timothy 4:7;  2 Peter 3:18 ).

In 2 Esdras 10:36 we have "Or is my sense deceived, or my soul in a dream?" Latin sensus , here "mind" rather than "sense."
