The Need to Move on to Maturity

5:11 On this topic we have much to say¹⁶ and it is difficult to explain, since you have become sluggish¹⁷ in hearing. 5:12 For though you should in fact be teachers by this time,¹⁸ you need someone to teach you the beginning elements of God’s utterances.¹⁹ You have gone back to needing²⁰ milk, not²¹ solid food.

¹tn The aorist participle περιβλεψάμενος (peribleyameno") has been translated as antecedent (prior) to the action of the main verb. It could also be translated as contemporaneous (“Looking around…he said”).

²tn This term is a collective singular in the Greek text.

³sn The passive was restored points to healing by God. Now the question became: Would God exercise his power through Jesus, if what Jesus was doing were wrong? Note also Jesus’ “labor.” He simply spoke and it was so.

⁴tn Some suggest a tolerative use of the Hiphil here, “[why do] you allow us to stray?” (cf. NLT). Though the Hiphil of תָעָה (ta’ah) appears to be tolerative in Jer 50:6, elsewhere it is preferable or necessary to take it as causative. See Isa 3:12; 9:15; and 30:28, as well as Gen 20:13; 2 Kgs 21:9; Job 12:24-25; Prov 12:26; Jer 23:13, 32; Hos 4:12; Amos 2:4; Mic 3:5.

⁵tn This probably refers to God’s commands.

⁶tn Heb “[Why do] you harden our heart[s] so as not to fear you.” The interrogative particle is understood by ellipsis (note the preceding line).

⁷tn Or “into the latrine.”

⁸tn Or “becoming aware of it.”

⁹tn Grk “Those of little faith.”

¹⁰tn Or “discussing.”

¹¹tn Here καί (kai) has been translated as “so” to indicate the implied result of the disciples’ inability to believe in Jesus’ resurrection.

¹²tn Grk “O,” an interjection used both in address and emotion (BDAG 1101 s.v. 1).

¹³tn The word “people” is not in the Greek text, but is supplied to complete the interjection.

¹⁴sn The rebuke is for failure to believe the promise of scripture, a theme that will appear in vv. 43-47 as well.

¹⁵tn On the syntax of this infinitival construction, see BDAG 364-65 s.v. ἐπί 6.b.

¹⁶tn Grk “concerning which the message for us is great.”

¹⁷tn Or “dull.”

¹⁸tn Grk “because of the time.”

¹⁹tn Grk “the elements of the beginning of the oracles of God.”

²⁰tn Grk “you have come to have a need for.”

²¹tc ‡ Most texts, including some early and important ones (א² A B* D Ψ 0122 0278 1881 Ï sy Cl), have καί (kai, “and”) immediately preceding οὐ (ou, “not”), but other equally significant witnesses (Ì⁴⁶ א* B² C 33 81 1739 lat Or Did) lack the conjunction. As it was a natural tendency for scribes to add a coordinating conjunction, the καί appears to be a motivated reading. On balance, it is probably best to regard the shorter reading as authentic. NA²⁷ has καί in brackets, indicating doubts as to its authenticity.
