   Present active forms in Matthew 19:14 and Mark 9:39 occur in commands not to bar children from coming or a person acting in Jesus' name; the APB renders these clauses with “hinder” and “prevent.” In Acts 10:47 the aorist active infinitive concerns withholding water from people about to be baptized, while Acts 16:6 uses an aorist passive participle for men having been stopped from speaking the word in Asia. The same restraint appears when people are hindered from speaking in 1 Thessalonians 2:16 and when death blocks continued service in Hebrews 7:23.
