AKJV(i)
16 And, behold, one like the similitude of the sons of men touched my lips: then I opened my mouth, and spoke, and said to him that stood before me, O my lord, by the vision my sorrows are turned on me, and I have retained no strength.
17 For how can the servant of this my lord talk with this my lord? for as for me, straightway there remained no strength in me, neither is there breath left in me.
18 Then there came again and touched me one like the appearance of a man, and he strengthened me,
19 And said, O man greatly beloved, fear not: peace be to you, be strong, yes, be strong. And when he had spoken to me, I was strengthened, and said, Let my lord speak; for you have strengthened me.
