1: Σωρεύω (Strong'S #4987 — Verb — soreuo — sore-yoo'-o )

"to heap one thing on another," is said "heaping" coals of fire on the head,  Romans 12:20 (for the meaning see COALS); in   2—Timothy 3:6 it is used metaphorically of women "laden" (or overwhelmed) with sins. See Laden. In the Sept.   Proverbs 25:22 .

2: Ἐπισωρεύω (Strong'S #2002 — Verb — episoreuo — ep-ee-so-ryoo'-o )

"to heap upon" or "together" (epi, "upon," and No. 1), is used metaphorically in  2—Timothy 4:3 of appropriating a number of teachers to suit the liking of those who do so. The reference may be to those who, like the Athenians, run about to hear and follow those who proclaim new ideas of their own invention.

Wilson's Dictionary of Bible Types [2]

 Proverbs 25:22 (a) There was a custom in Israel of lending coals of fire to a neighbor with which to rekindle a fire which had been allowed to die out. The neighbor carried the clay vessel on the head. When the neighbor desired to show special kindness to the one who wanted the coals, she would give an extra amount of these hot coals and fill the vessel that was carried on the head of her neighbor. By this she revealed her desire to be more than an ordinary helper. The Lord asks us to do this for those who need our help even though they be very unfriendly toward us. This act of kindness will win their friendship. (See  Romans 12:20).

 Habakkuk 2:5 (a) Here we are taught that some one will gather followers around himself who agree with him and his leadership.

 2 Timothy 4:3 (a) We learn by this figure that a false leader will invite folk to follow him, and those who are in false doctrines will invite false leaders to minister to them.

The Hebrew word גָּרַישׁ , Gadish', rendered " tomb" in  Job 21:32, and "heap" in the margin, properly signifies A Stack, A Heap, hence A Tomb, Tuzmulus, a sepulchral mound that was made by a pile of earth or stones. The ancient Tumuli were heaps of earth or stone, and probably such a pile was usually made over a grave as a monument. Travelers in the East have often seen heaps of stones covering over or marking the place of graves. The Hebrew phrase גִּל אֲבָנַים גָּרֹל gal abanim' gadol', rendered "a great heap of stones," refers to the heaps or tumuli which were raised over those whose death was either infamous or attended with some very remarkable circumstances. Such was the monument raised over the grave of Achan ( Joshua 7:26); and over that of the king of Ai ( Joshua 8:29). The burying of Absalom was distinguished by a similar erection, as a monument of his disgrace to future ages ( 2 Samuel 18:17). The same word גִּל , gal, is commonly used in reference to the heaps or ruins of walls and cities ( Job 8:17;  Isaiah 25:2;  Jeremiah 9:10). Modern travelers abundantly testify to the accurate fulfillment of Scripture prophecy in relation to the sites of numerous ancient cities, particularly of such as were doomed to become desolate Heaps (Bastow). (See Pillar); (See Stone). Other Heb. terms translated Heap are: חֹמֶר , cho'mer, a Pile ( Exodus 8:14, elsewhere a Homer as a measure); מְעַי , mei', a Heap of rubbish ( Isaiah 17:1); נֵד‘ , ned, a Mound ( Isaiah 17:11; poet. of waves,  Exodus 15:8;  Joshua 3:13;  Joshua 3:16;  Psalms 33:7;  Psalms 78:13); עֲרֵמָה , Aremah', A Pile (e.g. of rubbish, Nehemiah 3:34; of grain,  Song of Solomon 7:3; of sheaves,  Ruth 3:7;  Nehemiah 13:15;  Haggai 2:16, etc.); תֵּל , Tel, a Hill ( Joshua 11:13; espec. a mound of rubbish,  Deuteronomy 12:17;  Joshua 8:28;  Jeremiah 49:2, etc.); with others of a more miscellaneous signification. (See Mound).
