Discovery BoxRevelation 9:14 
Context9:14 saying to the sixth angel, the one holding 1 the trumpet, “Set free 2 the four angels who are bound at the great river Euphrates!”
Revelation 20:1
Context20:1 Then 3 I saw an angel descending from heaven, holding 4 in his hand the key to the abyss and a huge chain.
1 tn Grk “having.”
2 tn On λῦσον (luson) BDAG 606-7 s.v. λύω 2 states, “set free, loose, untie – a. lit. a pers., animal, or thing that is bound or tied…Angels that are bound Rv 9:14f.”
3 tn Grk “And.” Here καί (kai) has been translated as “then” to indicate the implied sequence within the narrative.
4 tn The word “holding” is implied. The two clauses “having the key of the abyss” and “a huge chain in his hand” can be construed in two ways: (1) both are controlled by the participle ἔχοντα (econta) and both are modified by the phrase “in his hand” – “having in his hand the key to the abyss and a huge chain.” (2) The participle ἔχοντα refers only to the key, and the phrase “in his hand” refers only to the chain – “having the key of the abyss and holding a huge chain in his hand.” Because of the stylistic tendency in Rev to use the verb ἔχω (ecw) to mean “hold (something)” and the phrase “in his hand” forming a “bracket” along with the verb ἔχω around both the phrases in question, the first option is preferred.
