'Same Day' in the Bible

In this self-same day went in Noah, and Shem, and Ham, and Japheth, sons of Noah, and Noah's wife and the three wives of his sons with them, unto the ark;

And Abraham taketh Ishmael his son, and all those born in his house, and all those bought with his money -- every male among the men of Abraham's house -- and circumciseth the flesh of their foreskin, in this self-same day, as God hath spoken with him.

in this self-same day hath Abraham been circumcised, and Ishmael his son;

till thy brother's anger turn back from thee, and he hath forgotten that which thou hast done to him, and I have sent and taken thee from thence; why am I bereaved even of you both the same day?'
