The Greek Behind "Shameless Audacity"
335 anaídeia (from 1 /A "without" and 127 /aidṓs, "shame") – properly, "shameless persistence" (Souter). 335 (anaídeia), used only in Lk 11:8, is literally "shamelessness" and relates to carrying out God's plan with "unembarassed boldness" – in the dignity of faith.
335 /anaídeia ("no shame, without embarrassment") is the shamelessness a faith-led believer has who is not be halted by human fears – even when others cry "overdone" (i.e. accuse them of being extreme or excessive).
Lk 11:8: "I tell you, if even he will not get up and give him anything because he is his friend, yet because of his shamelessness (335 /anaídeia) he will get up and give him as much as he needs."
