Pilgrim, I was surprised to find you did not believe in the doctrine of the impeccability of Christ. I respectfully offer a different view on this subject for consideration.

From Clinton Lockhart, Principles of Interpretation -
"If a translation be used, it must be an exact equivalent of the original, or the difference must be noted by the interpreter."

I find semantics an extremely important perspective or approach when understanding the truth of God's word, semantics being "the branch of linguistics and logic concerned with meaning."

The Roget's International Thesaurus, 7th Ed., 2010 indicates "tested" and "tried" are synonyms; but nowhere could I find in this thesaurus "tempted" shown to be synonymous with "tested" and "tried". It does indicate that "tested" and "tried" are synonymous.

The first and best presentation I've seen on the impeccability of Christ was in the theology of Robert L. Dabney in chapter 34, online you'll have to use "Find on Page" to locate "impeccability".

For what is's worth, from the BDAG -

"2 to endeavor to discover the nature or character of someth. by testing, try, make trial of, put to the test" ...

"B of God or Christ, who put people to the test, in a favorable sense (Ps.-Apollod. 3, 7; 7, 4 Zeus puts τὴν ἀσέβειαν of certain people to the test), so that they may prove themselves true J 6:6; Hb 11:17 (Abraham, as Gen 22:1). Also of painful trials sent by God (Ex 20:20; Dt 8:2 v.l.; Judg 2:22; Wsd 3:5; 11:9; Jdth 8:25f) 1 Cor 10:13; Hb 2:18ab; 4:15 (s. πειράω); 11:37 v.l.; Rv 3:10 (SBrown, JBL 85, 66, 30814 π.=afflict). Likew. of the measures taken by the angel of repentance Hs 7:1."
