Compound preposition 'because, for this reason'; emphatic causal particle reinforcing the ground of an assertion or action.
The phrase כִּי עַל כֵּן combines three particles into a single emphatic expression meaning 'because' or 'forasmuch as.' Found in a handful of memorable narrative moments, it reinforces the reason behind an action with a kind of pleonastic force -- literally 'for upon thus.' Abraham uses it when welcoming his three visitors at Mamre (Gen 18:5), and Lot echoes the construction when urging the angels to stay (Gen 19:8). Spanish translations capture the causal weight with 'por eso' and 'sobre,' while French renders it 'c'est pourquoi,' both confirming the grounding function. In one instance (Gen 33:10), Jacob's plea to Esau edges toward a consequential 'therefore,' drawing a conclusion rather than merely stating a cause.

Senses
1. Because / on account of (causal) The dominant causal usage, 'because' or 'on account of,' where the phrase emphatically grounds an action in a stated reason. In Gen 18:5 Abraham offers bread because his guests have come his way; in Num 14:43 Moses warns that the Amalekites stand ready because Israel has turned from the LORD. The pleonastic layering of כִּי + עַל + כֵּן gives the expression more rhetorical weight than a simple כִּי alone. Spanish 'por eso' and English 'because' converge across all nine occurrences.

2. Therefore (consequential / inferential) A rarer consequential or inferential shade, 'therefore,' where the phrase draws a conclusion from prior context rather than merely citing a cause. Jacob tells Esau in Gen 33:10 that seeing his face is like seeing God's face -- therefore he urges him to accept the gift. The shift from backward-looking cause to forward-looking consequence is subtle but real, and French 'c'est pourquoi' captures the inferential nuance.
