Esther 5:4

Let the king and Haman come this day unto the banquet. — It was natural enough that, with so much depending on her request, the queen should show some hesitation: if anything took an untoward turn (for, in spite of the king’s promise, she evidently felt uneasy) it might mean total ruin. She therefore temporises; she at any rate gains time, she secures a specially favourable opportunity for bringing forward the request, and the king clearly sees that she has kept her real petition in reserve by himself again raising the question. It will be noticed that so long as Esther is working her way up to the due vantage-ground, the king is addressed in the third person, let the king come,” but when she makes the decisive appeal, in the second, “in thy sight, O king.”
