Leviticus 23:5
4 “‘These are the Lord’s appointed times, holy assemblies, which you must proclaim at their appointed time. 5 In the first month, on the fourteenth day of the month, at twilight, is a Passover offering to the Lord. 6 Then on the fifteenth day of the same month will be the Feast of Unleavened Bread to the Lord; seven days you must eat unleavened bread.
LXX Leviticus 23:5
4 “‘These are the festivals to the Lord, and these festivals you shall call holy at their appointed times. 5 In the first month, on the fourteenth day of the month, in the middle of the evenings there is a Passover to the Lord. 6 And on the fifteenth day of this month is a Festival of Unleavened Bread to the Lord; for seven days you shall eat unleavened bread.
Notes and References
"... Quite surprisingly, the Septuagint rather than the Samaritan Pentateuch includes by far the largest number of harmonizations in Leviticus, especially in pluses. Altogether, the LXX contains 281 instances of harmonization, followed by the Samaritan text with 108 and the Masoretic text with a mere twenty-five instances ... In all of the Torah, the source that contains the largest number of harmonizations is the LXX. Possibly an equally large number was once contained in the pre-Samaritan scrolls, but at this point we only have fragmentary information for them ... The Septuagint stands out not only regarding the number of its harmonizations, but also in relation to their nature. The harmonizations in that source are more extensive than those in the Samaritan and Masoretic text ..."
