For if thou wilt now hold thy peace, the Jews shall be delivered by some other occasion: and thou, and thy father's house shall perish. And who knoweth whether thou art not therefore come to the kingdom, that thou mightest be ready in such a time as this?
Esther 4:12 And when Mardochai had heard this,
Esther 4:13 He sent word to Esther again, saying: Think not that thou mayst save thy life only, because thou art in the king's house, more than all the Jews:
Esther 4:14 For if thou wilt now hold thy peace, the Jews shall be delivered by some other occasion: and thou, and thy father's house shall perish. And who knoweth whether thou art not therefore come to the kingdom, that thou mightest be ready in such a time as this?
Esther 4:15 And again Esther sent to Mardochai in these words:
Esther 4:16 Go, and gather together all the Jews whom thou shalt find in Susan, and pray ye for me. Neither eat nor drink for three days and three nights: and I with my handmaids will fast in like manner, and then I will go in to the king, against the law, not being called, and expose myself to death and to danger.
The verse centers on "thou", "wilt", "hold", "peace", "jews", "shall", "delivered", and "some". It is saying that the verse draws attention to "thou" and "wilt", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 13's "He sent word to Esther again saying..." into verse 15's "And again Esther sent to Mardochai in...", so "thou" and "wilt" belong inside that flow. In Esther context, the local focus is covenant, worship, and faithfulness.
A plain takeaway is to answer the verse's own emphasis on "thou" and "wilt" with trust shaped by these words, not by a vague optimism outside the passage.
