Concise Bible Dictionary:

The word yesterday is used for the previous day (Ex. 5:1414And the officers of the children of Israel, which Pharaoh's taskmasters had set over them, were beaten, and demanded, Wherefore have ye not fulfilled your task in making brick both yesterday and to day, as heretofore? (Exodus 5:14); John 4:5252Then inquired he of them the hour when he began to amend. And they said unto him, Yesterday at the seventh hour the fever left him. (John 4:52); Acts 7:2828Wilt thou kill me, as thou diddest the Egyptian yesterday? (Acts 7:28)); and for past time indefinitely, as “a thousand years in Thy sight are but as yesterday;” and as when the Lord Jesus is said to be “the same yesterday, today, and forever” (Psa. 90:44For a thousand years in thy sight are but as yesterday when it is past, and as a watch in the night. (Psalm 90:4); Heb. 13:88Jesus Christ the same yesterday, and to day, and for ever. (Hebrews 13:8)). It is used also as if of “no duration,” as “we are but of yesterday” (Job 8:99(For we are but of yesterday, and know nothing, because our days upon earth are a shadow:) (Job 8:9)). Yesternight is the same as would now be called “last night” (Gen. 19:3434And it came to pass on the morrow, that the firstborn said unto the younger, Behold, I lay yesternight with my father: let us make him drink wine this night also; and go thou in, and lie with him, that we may preserve seed of our father. (Genesis 19:34); Gen. 31:29,4229It is in the power of my hand to do you hurt: but the God of your father spake unto me yesternight, saying, Take thou heed that thou speak not to Jacob either good or bad. (Genesis 31:29)
42Except the God of my father, the God of Abraham, and the fear of Isaac, had been with me, surely thou hadst sent me away now empty. God hath seen mine affliction and the labor of my hands, and rebuked thee yesternight. (Genesis 31:42)
