In John 20:17, μή μου ἅπτου is to be explained thus: Do not handle me to see whether I am still clothed with a body; there is no need of such an examination, for not yet etc.; cf. Baumg.-Crusius and Meyer at the passage (as given by Hackett in Bib. Sacr. for 1868, p. 779f, or B. D. American edition, p. 1813f).

c. with allusion to the levitical precept ἀκαθάρτου μή ἅπτεσθε, have no contact with the Gentiles, no fellowship in their heathenish practices, 2 Corinthians 6:17 (from Isaiah 52:11); and in the Jewish sense, μή ἅψῃ, Colossians 2:21 (the things not to be touched appear to be both women and certain kinds of food, so that, celibacy and abstinence from various kinds of food and drink are recommended; cf.

In classic Greek also ἅπτεσθαι is the stronger term, denoting often to lay hold of, hold fast, appropriate; in its carnal reference differing from θιγγάνειν by suggesting unlawfulness. θιγγάνειν, is used of touching by the hand as a means of knowledge, handling for a purpose; ψηλαφαν signifies to feel around with the fingers or hands, especially in searching for something, often to grope, fumble, cf. ψηλαφινδα blindman's buff. Schmidt, chapter 10.)).
