Based on Mark 6:52 we notice the disciples' observations of previously Feeding 5,000-men from 5-Loaves during [Mark 6:41-44] was considered "hard-hearted" since the disciples did not recognize Jesus of Nazareth as a supernatural "Christ" (Messiah) instead of a Prophet of YHVH like Elisha. So Jesus (after helping feed 5,000 men from 5-Loaves) has to prove he has greater power than normal prophets of YHVH by "walking on the sea" in [Mark 6:49].
Yet prior to Jesus' walk on water (instead of on dry land by parting water like most Neviim of YHVH), Were the disciples really hard-hearted in their pre water walk view of Jesus being similar to a Navi like Elisha?
Why [should] the feeding of 5,000-men from 5-Loaves be more miraculous or divinely Authoritative [to Jesus' Disciples] than Elisha's feeding of 100-men from 20-Loaves?
[Mark 6:52] "For they considered not the miracle of the loaves: for their heart was hardened." ( 6:52 οὐ γὰρ συνῆκαν ἐπὶ τοῖς ἄρτοις ἦν γὰρ ἡ καρδία αὐτῶν πεπωρωμένη )
- The disciples seem to innocently recognize Jesus of Nazareth as a Prophet of YHVH (like Elisha) - since אֱלִישָׁע Elisha had performed a similar miracle in 2 Kings 4:43.
[2 Kings 4:43] "His attendant replied, “How can I set this before a hundred men?” But he said, “Give it to the people and let them eat. For thus said YHVH: They shall eat and have some left over.” (וַיֹּ֙אמֶר֙ מְשָׁ֣רְת֔וֹ מָ֚ה אֶתֵּ֣ן זֶ֔ה לִפְנֵ֖י מֵ֣אָה אִ֑ישׁ וַיֹּ֗אמֶר תֵּ֤ן לָעָם֙ וְיֹאכֵ֔לוּ כִּ֣י כֹ֥ה אָמַ֛ר יְהֹוָ֖ה אָכֹ֥ל וְהוֹתֵֽר)
Why were Jesus' disciples hard-hearted in [Mark 6:52] for supposing Jesus' 5-Loaves for 5,000 men was equally miraculous and divinely Authoritative as Elisha's 20-Loaves for 100-men [2 Kings 4:43]?
